How to Learn (and Retain) Foreign Language Vocab

Learning vocabulary in a new language can be a really daunting task, especially when you think about the thousands (and that’s probably an understatement!) of words you have to learn. But language learning doesn’t have to be all boring rote memorization. In fact, unless you want to forget all these words the next day, it’s better not to just memorize blindly. In this post, I’ll introduce a few tricks you can use to efficiently learn and retain vocabulary. Psychological research has shown us that we learn best by association, so that’s what I’m going to preach here: 

1) Find cognates and borrowings from related language families

If you’re learning a language that’s related to English (say, a Romance language like Spanish or French, or a Germanic language like German or Dutch), it won’t take long to find several similar words.

Example: Let’s take the Spanish word la capacidad, or French la capacité.

  • From the way it’s spelled, we can see similarities to the English word, “capacity”.
  • Look at the parts of the word that differ between the languages: you get the English suffix -ity corresponding to Spanish -idad and French -ité.
  • Try it with other English -ity words and you’ll see a similar structure. For example, (“univers-ity” → univers-idad, univers-ité).
  • These words are also always feminine—that’s another small fact that you can store in your mind.

We’re lucky here because English happened to borrow a lot of “big” (that is, having to do with something cultural or scientific or political, etc.) words from French long ago, so if you’re learning any Romance language, you’re bound to come across these words. Even if a word doesn’t immediately look like an English word at first glance, see if you can find an etymology online that’s related to English.

Example: Take oog from Dutch, which means “eye”.

  • Looks pretty different right? But poke around the internet, and you’ll learn that some y’s in English go back to “g” (this was Old English ege), which looks closer to oog.
  • Think too, of the word ocular, which is from Latin, but take off the -ular adjective ending and you’ll see that oc- (Spanish ojo, French oeil) looks like oog and is indeed related. Making connections between related words like this will minimize what you’ll need to memorize.

2) Dissect the Words

Try breaking down words into smaller parts. Some languages are more conducive to this than others--Germanic languages, for example, tend to string together lots of smaller words.

Example: The word geben means “to give” (and sounds like it too).

  • From this root, we can form lots of words: vergeben “to forgive”, aufgeben “to give up”, ausgeben “to spend, give out”.
  • Now we can look at the prefixes ver-, auf-, and aus-. Do they look familiar? Maybe not at first glance, but I’ll tell you a secret--they’re related to English “for”, “up”, and “out”. Knowing this will tell you a lot already. “For-give” matches perfectly, while “up-give” and “out-give” will match if you switch the parts around. Cool trick, right?
  • Combining the dissecting of words with tip #1 (looking for cognates and borrowings) will carry you far. Examining the structure of a word is like learning how a machine works by looking at its parts. It’ll help you learn new words, too.

3) Use Mnemonics (especially for words unrelated to English)

If all else fails, use mnemonics (which, by the way, is related to the word for “memory”). Think up something completely ridiculous and it’ll stick with you! 

A friend once told me that his teacher told him to remember the word “celerity” (which means “speed”) by imagining a celery stalk running down the street. It sounds completely ludicrous, but to this day I associate the meaning of “celerity” with that imagery. You can do this with other languages too, especially ones that aren’t related to English.

Example: Let’s look at the Korean word for “ashtray”, which is jetteolli.

  • Because it sounds like Jet Li, I like to imagine him smoking a cigarette. There’s my connection!
  • We’re more likely to remember weird things than mundane things, so cook up ridiculous images for those hard-to-remember words; like the “celerity” example shows, this can be useful for learning SAT words too!


The key here is to use what you already know to draw connections to new words. If you just aim for rote memorization, you’re continually forming new memories and wasting working memory space. Instead, form word associations. Not only is it more efficient and fun, it will also stick with you longer!
