The Keyword Method: Linking New Words to Sounds You Already Know
By the end of this guide you will be able to turn a foreign word that keeps slipping away into a two-part memory hook: a sound link and a picture link. The keyword method is a vocabulary mnemonic (a memory aid) that borrows an English word you already know and uses it as a bridge to the new word.
This page is the technique guide, not a whole vocabulary plan. For choosing words, card design and review, see how to memorize vocabulary. Here we cover how the method works, three examples, what the original experiments reported and where the method stops being useful.

The two links: sound first, then picture
Atkinson describes the method as two steps. The first is the acoustic link: find an English word, the keyword, that sounds like part of the foreign word. The second is the imagery link: build a mental image in which the keyword and the English translation interact (Atkinson, 1975).
- Say the foreign word aloud and listen for a chunk that sounds like an English word.
- Choose that English word as your keyword. Concrete nouns, such as pot or shovel, are the easiest to picture.
- Build one image in which the keyword and the translation do something together.
- Test yourself in a chain: foreign word, keyword, picture, translation.
The keyword does not have to sound identical. A close match on the stressed part of the word may be enough, but that rule of thumb is our own practical advice, and so is the tip about concrete nouns. The studies we cite did not test either one.
Three examples in three languages
These keywords and images are ours, chosen for a US English accent. If a keyword does not sound close to you, replace it with one that does.
| Foreign word | Meaning | Sound-alike keyword | Picture that joins them |
|---|---|---|---|
| pato (Spanish) | duck | pot | A duck wearing a cooking pot as a hat. |
| cheval (French) | horse | shovel | A horse digging a hole with a shovel. |
| Fenster (German) | window | fencer | A fencer lunging through a window. |
What the research reports, and its limits
Atkinson's 1975 article summarizes experiments from his own laboratory. In a Russian-vocabulary experiment, the keyword group recalled more words than the control group on a comprehensive test and on a delayed test six weeks later. The article also reports that the keyword group did better in a Spanish-vocabulary experiment in which control participants used rote rehearsal (Atkinson, 1975). The vocabulary was presented by computer in laboratory settings, so the results do not tell us how the method works in a busy classroom.
Later, a major review of ten learning techniques rated the keyword mnemonic as low utility. The authors judged it to be limited, since it appeared to help for a limited number of materials and short retention intervals (Dunlosky et al., 2013).
Read together, the two sources support a modest conclusion. The method can help with some vocabulary in the laboratory. It is a narrower tool than a habit such as practice testing, which the same review rated as high utility. We make no promise about vocabulary results, and they vary between people.
Where the method breaks down
| Limit | What goes wrong | Workaround |
|---|---|---|
| Abstract words | A word for an idea has no obvious picture. | Picture a concrete stand-in, or skip the method for that word. This is practical advice, not a tested result. |
| Accent | An English keyword hides sounds that English lacks, such as the French vowel in rue (street), which an English roo only approximates. | Learn the real pronunciation from audio first and keep the keyword only as a hook. |
| Grammar | The chain links one word to one meaning. It does not carry gender, endings or word order. | Cover grammar with separate cards and example sentences. |
| Wrong direction | You may be able to go from the foreign word to the meaning but get stuck going back. | Test both directions, because the chain is built for one of them. |
The method also takes effort for every single word. If a word sticks without a trick, leave it alone and save the method for the stubborn few. For more on how mnemonics can disappoint, see when mnemonics fall short.
A same-day routine for stubborn words
- Collect five words that you keep missing on ordinary cards.
- Build a keyword and an image for each, using the table above as a model.
- Put each word on a card: the foreign word on the front, and the meaning plus a short note of your keyword and image on the back.
- Quiz yourself in both directions tomorrow, and drop any keyword that confuses you.
You can keep those cards in Practice, which schedules each card in one of five boxes with waits of 1, 2, 4, 8 and 16 days. The pictures themselves are the subject of our guide to mental imagery, and the wider family is in what mnemonics are.
Common mistakes
- Choosing a keyword that sounds only loosely like the foreign word. Match the stressed part of the word, then say both aloud. If you hesitate, pick another keyword.
- Using abstract keywords that cannot be pictured. Pick concrete nouns: a pot, a shovel, a fencer. Concrete words make an image easy to build.
- Making the keyword and the translation sit side by side. Make them interact in one action, such as a horse digging with a shovel.
- Never testing the reverse direction. Quiz yourself from the meaning to the foreign word as well, so the hook does not cover only half the job.
Frequently asked questions
What is the keyword method?
It is a two-step vocabulary mnemonic. You link the foreign word to a sound-alike English keyword, then link the keyword to the English meaning with a mental image (Atkinson, 1975). It needs no drawing skill, only a sound-alike and a picture that you can hold in your mind.
Does the keyword method work?
In Atkinson's Russian-vocabulary experiment, the keyword group recalled more words than the control group, including at a delayed test six weeks later. A later review judged that the method appeared to help for a limited number of materials and short retention intervals (Dunlosky et al., 2013). Results vary between people.
Can I use it for every word in a new language?
It takes effort to build for each word, and concrete words are easier to picture than abstract ones. Use it for the few words that resist ordinary cards, and handle the rest with spaced review.
Do I need the keyword to match exactly?
No. A close match on the stressed sounds is a sensible target. If the match is loose, say both words aloud and see whether one calls up the other. That is practical advice, not a finding from the studies we read.
