Greek and Latin Roots: “B” Base Words

Our next stop through classical root words is “B.” It’s a short list this time around! Again, these are all taken from Appendix C in Greek and Latin Roots: Keys to Building Vocabulary, with some small changes of my own in the “Example” column. You can see the “A” words here.

Remember, these are base words, or stems: these are the main “chunks” onto which affixes are added, rather than actual affixes.

Base Meaning Example
barbar savage; savagery barbarian
bell(i), bellum war belligerent, antebellum
bi(o) live, life biography, biology
bibli(o) book bibliography
bol throw symbol
bon, bene good, well bonanza, benefit
bov cow bovine
brev short abbreviation
bys bottom abyss

Greek and Latin Roots: “A” Base Words

I’d like to return to my series on affixes for a while and talk about Greek and Latin roots. These roots refer not only to affixes, but base words (also called “stems”; these are the main word to which affixes or prefixes are added) as well.

Again, for teachers, I would still highly recommend the book Greek and Latin Roots: Keys to Building Vocabulary. For students, I would like to feature what is probably the most useful chunk of the book here: common classical roots of English vocabulary. All content here, while essentially common etymological knowledge, I’m taking from Appendix C of Greek and Latin Roots, with periodic changes in the sample words (just because I felt like it). Since I’ve already talked (to an extent) about affixes, I’d like to start with base words. No Swedish translations are given this time, as they would be much more difficult to sort, and not nearly as helpful.

Base Meaning Example
(a)llel one another parallel
ag, act, igu drive, go agile, action, ambiguous
adelph brother Philadelphia (“the city of brotherly love”)
aer(o) air, wind aerate, aerobic
agog(ue), agogy lead (verb) pedagogy, synagogue
al, alma nourishing alimony, alma mater
alg pain, ache nostalgic, analgesic
am(a), amat, amor love, friend amiable, amateur, amorous
ambul walk ambulatory
angel messenger angelic
angle angle triangle, quadrangle
anim life, soul animate
annu, enni year annual, perennial
anthrop(o) human being, mankind anthroplogy
ap(i) bee apiary
aqu,aqua water aqueduct, aquarium
aquil eagle aquiline
astr(o) star astronomy
athl contest, struggle athlete
audi, audit hear, listen audience, audition
avi bird* avian, aviator

*Note that this one has also become synonymous with flight; while “avian” means “pertaining to birds” and an “aviary” is large, enclosed space to keep birds, an “aviator” is not a bird, but a human being who pilots an airplane (or other flying machine).

If the sample words are new to you, or you’re not sure how they connect to the meaning of the base word, I recommend looking them up in the Online Etymological Dictionary.

Tatoeba Tips

Tatoeba began as the brain child of Trang, inspired by the English–Japanese website The name “Tatoeba” even comes from the Japanese word for “for example.” You can read more about the history of on Trang’s blog, but the long and short of it is: Tatoeba is a collection of open source, community-generated sentences in multiple languages—something like a huge, global phrasebook. These sentences can be a great resource in your language study. But Tatoeba can also be overwhelming at first, so here are some tips to get you started.

1. You should probably register.

The nature of Tatoeba is such that everyone can browse it and look up sentences; registering allows you to contribute translations, add your own sentences, and (eventually, if you decide to ask for such privileges) tag and link sentences. If you’re just curious about a word now and then, you probably don’t need to sign up. But if you want to dig deeper, you’ll need a proper account. (It’s free!)

Note that Tatoeba, unlike Lang-8, doesn’t make a clear distinction between your native language and the languages you’re studying; rather, you list any languages you can speak, and then rate your fluency in them, from “almost no knowledge” to “native level.” So go ahead and add everything you’re interested in and know about. Here are mine, for example:


There is no limit to how many languages you can have in your account, and there’s no fluency requirement, so add as many as you like. My Korean, for example, is in absolute shambles, but since I at least know how to read Hangul, I listed it (and then put it at level 0: “almost no knowledge”).

2. Learn to use the search function.

Tatoeba uses Sphinx Search to account for all of the complexities of language. It’s mostly intuitive, but there are some wrinkles to be aware of. You can learn more at the Tatoeba Wiki.

Sphinx Search relates to the search bar at the top of the page. This search focuses just on the content of sentences, looking for actual, literal words. If you’re interested in a particular category of words, such as sports or politics or weather, you can search the tags instead. This search function is much less complex and does not use the same operators as Sphinx Search.

3. Add sentences.

If you want to improve Tatoeba (and of course you do, right?) and you have the time, you can also add sentences of your own. There are two ways to do that.

First, you can simply add a sentence directly to the corpus. Tatoeba even helpfully suggests vocabulary that hasn’t yet been featured on the site, so you can maximize your helpfulness by focusing specifically on those words.

The other way you can add sentences is by translating sentences already in the corpus.

When you’re looking at sentences on Tatoeba, you’ll see a little symbol in the upper left corner of every sentence, like this:


This is the option to translate. It’s not necessary (and even, arguably, flat-out unhelpful) to give a translation that’s identical to what’s already on the site. (Alas, there’s also no upvoting/approval system like there is on Lang-8, so there’s no good way to tell if a given translation is good or bad.) But if you look at sentence and see that it doesn’t have a translation in a language you know well, or the other translations are awkward or inadequate, then you can feel free to add one! When you click that symbol, a little box comes up:

I’m not actually brave enough to try to translate this into English. Yet.

Tatoeba also uses indirect (from L1 to L3 by way of L2) translations. It distinguishes between direct and indirect translations with blue arrows (indicating direct translations) and gray arrows (indirect translations). But you have to be careful: if you decide to translate something indirectly, make sure you click the translation you’re working from first. This will take you to a new page where that L2 translation is the “main sentence,” rather than just a translation. That way, your L3 translation is appropriately marked on the original L1 sentence as an indirect translation, and the code stays neat and tidy. (You can read more about Trang’s philosophy here.)

The principle of translating on Tatoeba is sentences and meaning, rather than word-for-word correspondence. “I’m 25 years old” is not, technically, a word-for-word translation of French (“I have 25 years.”) or Russian (“To me there are 25 years.”), but it’s how native speakers would express the idea of being 25 years old, so it’s the best (and only) possible choice.

4. Submit high-quality work.

Tatoeba is not a playground, or an opportunity for feedback/error correction. When you submit a translation or a sentence, you are submitting study material for other learners to use. This is why Tatoeba stresses that you only add translations and sentences only in languages in which you have fairly high levels of competency. Anything else—grammar or vocabulary practice, writing practice, proofreading—is better saved for elsewhere, such as Lang-8.

That’s Tatoeba in a nutshell! I’d like to shout out to my friend Yousef, who was the first to alert me to the existence of Tatoeba. It’s a great project but a little overwhelming, so if you need help (or if I missed anything), comment below or let me know on Twitter!


English Vocabulary With Affixes: Using Affixes to Make Adjectives

This is the fourth and final post (for now) in my affixes series. There are a lot more affixes in English than I’ve covered here, but as this part of the series wraps up the list over on UEFAP, it feels like a natural stopping point.

This post will cover using both prefixes and suffixes to create new adjectives, as well as their Swedish equivalents.

1. Noun + Suffix = Adjective; Verb + Suffix = Adjective

Suffix Meaning Swedish equivalent
-al relating to a noun (central, professional) -al (central), -ell (professionell), -sk (politisk)
-ive relating to a verb (imaginative, effective) -iv (attraktiv)
-ful having or being full of a noun (beautiful, careful) -full (fridfull)*
-less lacking a noun (endless, homeless) -lös (tanklös)*
-able / -ible to be able to verb (drinkable, countable) -bar (ätbar)*

*indicates a group of adjectives that often have -lig or –ig adjective endings in Swedish

2. Negative Prefix + Adjective = Opposite Adjective

Note that all of these prefixes have the same essential meaning and job—to reverse the meaning of the root word. It’s simply that some root words take one prefix and some take another. To avoid redundancy, I’ve omitted the middle column for this last table.

Prefix Swedish equivalent
im-/in-/ir-/il- (immature, inconvenient, irreplaceable, illegal) o- (omjölig)
non- (non-fiction, non-political) o- (obefintlig), non- (nonstop), icke (a full-fledged word, not a suffix)
dis- (disloyal, dissimilar) o- (oärlig)
un- (unfortunate, uncomfortable) o- (orättvist)

Though you can see that this whole table is largely redundant, as a large number of English prefixes fall under the o- umbrella in Swedish. This certainly simplifies things for English-speaking learners of Swedish, but complicates things for Swedish-speaking learners of English!

There is much more to English affixes than what I’ve been able to cover so far, of course. And I’m far from an expert in either linguistics or Swedish! As I progress in my own studies, I will update here. Good luck with your own learning!

English Vocabulary With Affixes: Using Suffixes to Make New Nouns

This is the next part in my series on English affixes and their Swedish equivalents. You can start with part 1 (an introduction, and using prefixes to alter verb meanings), and also check out part 2 (using prefixes to create new nouns). This time, I’m focusing on creating new nouns out of a verbnoun, or adjective by way of a suffix. This process can be classified into three groups: nouns from verbs, nouns from other nouns, and nouns from adjectives.

I’ve taken the English list from UEFAP, but all of the Swedish translations are my own. This and all other posts on affixes will probably be edited as my Swedish improves. Sometimes there’s not really a Swedish equivalent; in those cases, I just skip to the next. Also note that there is rarely a true 1-to-1 correspondence; what I list here are what (in my experience) are the most common equivalents.

1. Verb + Suffix = Noun

English suffix Meaning Swedish equivalent
-tion,  -sion an action/instance of the verb (alteration, demonstration) -tion (dedikation)
-er a person who does the verb / something used for the verb (advertiser, silencer) -ör (redaktör), -are (ägare)
-ment an instance of the verb (development, punishment) -ing (utnämning)
-ant,   -ent a person who performs the verb (assistant, student) -ent (student), -ant (officiant)
-ence, -ance the act of the verb, or the result of the verb (dependence, endurance) -ans (acceptans)*
-ery,   -ry an action or instance of the verb (bribery) or a place where the verb happens (bakery) -eri (raffinaderi)*

*indicates a suffix that is often also -ing in Swedish, instead of a close 1-to-1 correspondence with English

2. Noun + Suffix = New Noun

English suffix Meaning Swedish equivalent
-er person associated with the noun (astronomer, geographer) -are (juvelerlare)*
-ist person associated with the noun (biologist, scientist) -ist (buddist)*
-ism doctrine of a noun (Maoism, materialism) -ism (buddism, marxism)
-ship state of being the noun (friendship, citizenship) -skap (ledarskap)

*indicates situations where, if the base noun ends in “i,” the “i” is removed but no suffix is added (astronomi -> astronom, biologi -> biolog)

3. Adjective + Suffix = Noun

English suffix Meaning Swedish equivalent
-ity, -ness, -cy state or quality of being the adjective (ability, similarity) -het (nyfikenhet, gulhet), -itet (graviditet)

To a lesser extent in this category you see -skap (beredskap), -ing (besittning), and a handful of others, but in my experience -het and -itet are the most common.

English Vocabulary With Affixes: Using Prefixes to Make New Nouns

This is part 2 of an ongoing series about common English affixes and their Swedish equivalents. You can find part 1 here: using prefixes to make new verbs.

I’m using the most common prefixes, as compiled by UEFAP. Today’s segment is about using prefixes with nouns to make new nouns. When it comes to the Swedish translations of this prefixes, you’ll notice that they’re often identical or close enough. This list, and other upcoming posts on affixes in English and Swedish, is not a complete list! (For a more complete list, refer to the above UEFAP link.) These are simply the ones that have something like a Swedish equivalent.

Prefix English meaning Swedish equivalent
anti- against (antibiotic, antithesis) anti (antiklimax), mot (motgift)
auto- self (automobile) auto (autobiografi)
counter- against (counterargument, counterattack) mot- (motargument)
dis- the converse or opposite of (discomfort, dislike) o- (obehag, olust), av- (avsmak), mot- (motvilja)
hyper- extreme (hyperactive hyper (hyperinflation)
in- converse or opposite of (inattention, incoherence) in- (inkompatibilitet), o- (oförenlighet)
inter- between (interaction) inter- (interaktion)
kilo- thousand (kilobyte) kilo- (kilogram)
mega- million (megabyte) mega- (megabyte)
mis- wrong (misunderstanding, misapprehension) miss- (missförstånd)
mono- one (monoculture, monogamy) mono- (monoton)
neo- new (neoliberal) neo- (neonatal)
poly- many (polyphony) poly- (polygraf)
pre- before (prefix) pre- (prefix), för(e) (förord, företal)
pseudo- false (pseudoscience) pseudo- (pseudonym)
semi- half (semi-completeness) halv- (halvcirkel), semi- (semikolon)
sub- below (subset) under- (underavdelning)
super- more than (superpower), above (supervisor) över- (överflödig), stor- (stormakt)
tele- distant (television) tele- (telesystem)
under- below (undergraduate), too little (underpayment) under- (underplagg)
vice- deputy, assistant (vice president) vice- (viceordförande)

English Vocabulary With Affixes: Using Prefixes to Make New Verbs

In English, as in many other languages, it’s possible to create new words out of a basic root word (kind) by adding affixes. Most of the time in English, you’ll see prefixes (unkind) and suffixes (kindness). We also have a handful of simulfixes, but those might better thought of as spelling rules (man -> men) rather than as affixes. You can read more about the classification of affixes here, along with examples from different languages.

With any new student at the intermediate level, especially if they’re using English to further their studies, I talk about English affixes right away. When you have an English test in front of you, you probably don’t have time to look up every new word—in fact, you might not be allowed to look up any words at all. Being able to recognize affixes and connect them to meaning and function can be the difference between a confident, educated guess on a question and a coin toss. I’ve found that even students at a fairly high level might not have had a solid, sit-down lesson on these little word bits. So they learn happy and sad, and maybe learn unhappy as a synonym for sad, and they might notice the pattern of unhappy, unbelievable, untrue, and unseen as they learn new words and progress in their studies…or they might not.

Root words and affixes are the building blocks of English vocabulary.

Over at UEFAP, Andy Elliott has done an incredible job of organizing English affixes by transformative ability. This is great information to add to your study routine (maybe by making a specific Anki deck?).

But remember to also study any possible false friends or points of confusion as well. While undersell and undervalue sound exactly how they mean, we know that understand doesn’t mean that you’re not on your feet enough! 😉 And remember that we have both warmness and warmth, but only coldness (no coldth).

I’ve taken the liberty of translating the affixes over at UEFAP into their Swedish equivalents. They’re similar, but it’s not always a one-to-one translation. It’s also quite a thorough list, so I’ll be sharing and translating in parts. This first piece concerns prefixes that alter verb meanings. Note that sometimes these verbs with the prefix are standalone verbs, and that the original root verb no longer sees usage, or has a meaning slightly different from the prefix + root word version.

Prefix English meaning Swedish equivalent
dis- negation or opposite (disappear, disappoint) o- (ogilla), av- (avskida)
re- again (redo, reapply) för- (förnya), åter- (återskapa)
over- too much (overwork, overcharge) över (överanstränga)
mis- incorrectly or wrongly (misuse, miscalculate) mis- (misräkna), fel- (felbedömma)
out- greater or more than (outnumber, outmaneuver) ut- (utmanövrera), över- (övertraffa)
co- together (cooperate, coexist) sam- (samarbeta)
inter- between (interconnect, interact) inter- (intervjua)
tran- across, over (translate, transfer) över- (översätta)
under- too little (undersell, underperform) under- (undersälja)

Thoughts on DuoLingo

There are lots of free online language-learning tools, but the one I see used most often is DuoLingo, so that’s where I’m going to start in my survey of web-based language portals.

What Is DuoLingo?

DuoLingo is a free language-learning website and app. Today, I’m only focusing on the website, as that’s what I use myself.

As of now, you can use the site in 21 different languages and study up to 16. It looks like the native English version of the site has the most languages available out of any other, including niche offerings like Welsh or Esperanto. For everyone else, the choice is a little more limited and is usually English. I think it’s pretty safe to infer that many of DuoLingo’s users are using it to learn English.

Languages available for English speakers to study on DuoLingo

DuoLingo is built on translating simple sentences. Exactly what is available seems to depend on the language, but the basics include:

  • translating a sentence from the target language into your native language, and vice versa
  • multiple choice questions
  • simple clozes (fill-in-the-blanks)
  • dictation

In some lessons there’s also a speaking portion, if you care to use your mic. (I don’t have it in Russian, but my partner has it in Italian.)

DuoLingo is free to use.

What Do I Like About DuoLingo?

It’s free! And for being free it’s a pretty great resource. It attempts to address all four areas of language acquisition (speaking, listening, reading, and writing) and every exercise has a discussion thread attached to it, allowing you to get feedback from experts and native speakers about why a particular answer is or isn’t correct. DuoLingo’s userbase is so large that any question you ask will probably be answered fairly quickly.

The focus of each lesson is also sufficiently narrow to keep from overwhelming the true beginner, while the level tests allow a false beginner to skip ahead to an appropriate level/lesson instead of going over the basics yet again. And it generally seems pretty forgiving on spelling (unless spelling is an essential part of the grammar).

DuoLingo also encourages daily practice. In whichever language you study, you set yourself a goal of how many points you want to earn a day. You can set it low if you want to keep things casual, or if you’re serious you can set it quite high. If you use Chrome (or Chromium) and allow DuoLingo to use your alerts, the site will nag you if you haven’t hit your daily goal yet. You also get rewarded for streaks.

DuoLingo gives you a weekly summary of your activity.

Finally, the whole thing is built on daily practice and a spaced repetition model. The site shows you exactly which areas you need to review and which you don’t, according to models that I assume are based on your previous performance and how long it’s been since you reviewed a particular lesson.

How I'm doing in Russian. You can see that I need to review "prepositions and place," "family," "people 2," and "nature."
How I’m doing in Russian. You can see that I need to review “Prepositions and Place,” “Family,” “People 2,” and “Nature.”

What Don’t I Like About DuoLingo?

It focuses almost exclusively on simple sentences, or at most two or three. This is fine for learning new vocabulary or grammatical structures, but won’t help your long-form reading (or writing) skills. Also, some of the sentences are surreal to the point of uselessness. (“There are many problems from his houses.” is one that springs to mind from the Russian for English speakers series.)

I believe language acquisition works best when you’re able to use it talk about, well, you! Yourself and things you care about. With DuoLingo, you are an incredibly passive participant, with zero input into the direction of the lessons.

The quality of lessons also seem to be inconsistent across languages. There are lots of cool options available to my partner in the Italian tree that I don’t have in Russian, like using lingots to purchase bonus lessons on idioms or pick-up lines. Likewise, I can’t guarantee the quality of any other lesson, because it seems to depend at least partially on your native language.


DuoLingo is really good for learning vocabulary and essential grammar concepts. But no matter what your level is, you should be supplementing it with other material: music, movies, or podcasts; short stories, essays, or news articles; conversation classes or Skype sessions; writing your own work. These last options require clear and useful feedback, something a good teacher can provide.

Tips For Getting The Most Out Of Anki

I first came across Anki in Gabriel Wyner’s Fluent Forever. It’s a whole treasure trove of language-learning tips, but the bulk of Wyner’s philosophy revolves around flashcards, Anki, and spaced repetition. I couldn’t begin to summarize the book in a single blog post, so I’ll just recommend it. Wyner is sometimes a bit too gung-ho about all the great tools he wants to sell you, but Fluent Forever is no less helpful because of that.

Wyner sings the praises of Anki, and since the Droid version is free, I thought I’d give it a shot. I’m currently studying Russian, so it came along at the perfect time. Once I got the hang of creating the cards, and got my smartphone synced up with my desktop version, things were a breeze.

Flashcards are for more than mere vocabulary, however. Here are a couple of different ways I would recommend using Anki in your English study—aside from vocabulary.

(Note: I assume that you have a copy of Anki and that you’re comfortable using it. If you’d like more details on how to customize Anki, you can refer to their manual. Another good guide is this one from Alex Vermeer.)

1. Spelling Help

If you struggle with English’s semi-random yet semi-predictable spelling, you can offload the problem on to Anki.

The first step is being aware of the mistakes you make the most consistently. Maybe you have issues with -sion versus -tion, for example. Or maybe you struggle with irregular verbs: not eated but ate? not runned but ran? Put them in Anki.

You can just use a basic card with, say “eat” on the front and “ate” on the back. Or maybe “b__t (thing on water)” on the front and “boat” on the back. If you feel comfortable typing within Anki, you can set up the card so that you have to type in an answer (rather than just think about it). Anki will then display the correct answer and highlight any mistakes you may have made. For more about how to design Anki cards with typing input, see this how-to video.

I would recommend this method if it all possible. If not, try to keep scrap paper on hand to write on while you study so you can write out the correct spelling yourself. If you don’t have that, then you can move your hand as if you were writing, or imagine writing the answer. Or spell out in your head, like in a spelling bee. The more you do something yourself, or the more you think through the steps of doing something yourself, the better you learn something and the less likely you are to fall into the trap of just assuming you know something.


2. Listening And Pronunciation

How's your English listening?

Learning the phonemes of a language—its individual, component sounds—is maybe one of the most difficult parts of learning a language. Usually we struggle with sounds in a language because we can’t distinguish them from other sounds, whether in our native language or the target language. I have a tough time with å and o in Swedish, for example. You can use an Anki deck to blitz the difference between them.

Wyner has a number of useful Anki card templates available for download from his site. The template you’d want for this would be his “minimal pairs” template. If you want to make your own, though, you can. But whether you’re customizing Wyner’s template or creating your own, you’re going to be doing a lot of research and input.

First, collect a bunch of words that share your “struggle sounds.” A typical pair of problem sounds in English for many learners is short “i” and long “e” (ship / sheep, chip / cheap), for example. Find recordings from, and then very carefully apply them to cards (you want your recordings to match their answers!) in a pattern like this:

Front: ship or sheep? [sound file: ship]

Back: ship

Front: ship or sheep? [sound file: sheep]

Back: sheep

If you allow the cards to be reversed, you can practice your pronunciation as well as your listening: the word “ship” or “sheep” will come up, and you can compare your pronunciation with that of the recording. Of course, sometimes it’s hard to hear how close you are to a particular sound. That’s where a teacher comes in handy.


3. Grammar Blitz

Tips for studying English grammar with Anki.

There are so many ways you can do this. I’ll just share a small bit of my personal method and hopefully it will inspire you.

I use Anki to study Russian. Where modern English has only three cases (“grammar jobs,” for lack of a better word), Russian has six. Learning all of the ways that a personal pronoun can change depending on the job it has to do is just half the battle—when do you use each case?

First, I sat down and worked out a color scheme for all of the cases. So prepositions or verbs that require the accusative case (“him” in English) are dark blue, and prepositional cases (“by him”) in red, and so on.

Then, when it came to making the cards, I put phrases (“with him,” “without money,” “to the park,” and so on) on one side of the flashcard, with the Russian preposition in its appropriate color and whatever noun in its nominative form. The right answer is to 1) have a correct English translation of the preposition and 2) to know the proper form of the noun (and any attendant adjectives).

The other side of the card has the English translation of the preposition and the appropriate form of the noun (in its matching color). The right answer is the Russian translation of the preposition.

You can apply this similarly to English. If you struggle with catenative verbs and remembering which ones take a gerund, which ones take just the verb stem, and which ones take the “to” infinitive, you can come up with your own color code and little phrases and review those in a similar manner.

(I find it helpful to relate the color to the grammar point in some way. For example, my genitive case prepositions are in green, and instrumental in indigo. You want the color associations to be quick and easy! So in this case maybe green for gerund, taupe for “to” infinitive, and silver for stem. But it depends, of course, on the color names in your native language.)

So those are just a few ways you can use Anki beyond simple vocabulary. Do you have any other tips or tricks? Share them in the comments, or tweet @KobaEnglish!
