How to Keep a Vocabulary Notebook That Works

A good vocabulary notebook records more than a word and its translation. For each word, write its pronunciation, a short definition in your own words, an example sentence and the words it usually goes with. Then organise the notebook so you can find words again and test yourself on them. A notebook you never open again is just a list.

This guide covers what to write, how to lay out each entry, and how to keep the notebook useful for months, not just for the first week.

What to write for each word

Most notebooks fail because each entry is too thin. "Reliable = trustworthy" tells you the meaning, but not how to use the word. A complete entry has six parts.

1. The word and its part of speech. reliable (adjective). Knowing the word type tells you where it goes in a sentence. If you're unsure about word types, the adjectives lesson is a good place to start.
2. Pronunciation. Write it in a way you'll understand later: the dictionary's IPA (/rɪˈlaɪəbl/), or your own note on the stressed syllable (re-LI-able). Stress mistakes are a common reason people don't understand a word they actually know.
3. A short definition in English. Keep it simple: "can be trusted to do what is expected". Writing the definition in English, even a rough one, helps you think in English instead of translating.
4. A translation. Your native language is a fast way into the meaning, and it's especially useful for abstract words. Just don't let it be the only thing you write.
5. An example sentence. Keep the sentence where you found the word, and add one of your own: "My old laptop isn't very reliable, so I save my work often."
6. Word partners and forms. The words it often appears with, and its family: a reliable source, reliable information; rely on (verb), reliability (noun), unreliable (opposite).

That's a lot to write by hand for every word, which is why it pays to be selective about which words go in (see below).

A layout you can copy

On paper, give each word a block of four or five lines and leave space under it for later notes. Here's a full entry:

reliable (adj.) · /rɪˈlaɪəbl/ · re-LI-able

• Meaning: can be trusted to do what is expected
• Translation: (in your language)
• Found: "The bus service here isn't very reliable."
• Mine: "My old laptop isn't very reliable, so I save my work often."
• Partners: a reliable source, reliable information · rely on · unreliable

Notice the preposition in rely on. Small words like this are where many mistakes come from, so mark them clearly. The same goes for nouns: write down whether a noun is countable (an idea, two ideas) or uncountable (some advice, never an advice). The countable and uncountable nouns lesson explains the difference.

How to organise the notebook

There's no single right structure, but pick one and keep it. Three approaches work well.

• By date. Add words in the order you meet them, and write the date at the top of each page. This is the easiest to keep up, and it makes review simple: "today, test the words from last week."
• By topic. Separate sections for work, travel, health, feelings and so on. This helps when you're preparing for something specific, like a job interview, but you'll have to decide where each word belongs.
• By source. One section per book, course or series you're learning from. This keeps the original context close to every word.

Whichever you choose, add one more thing: a way to mark how well you know each word. A simple system is a dot next to the word each time you recall it correctly without looking. Words with no dots need attention. Words with three dots can be reviewed less often.

Choose words worth writing down

You can't write a full entry for every unfamiliar word you see, and you shouldn't try. Before adding a word, ask:

• Have I seen it before? A word you have met two or three times is probably common, so it's worth learning.
• Would I actually use it? Reliable is useful in almost any conversation. A rare technical term from one article probably isn't, unless it's from your field.
• Is the meaning clear from context? If you understood the sentence without the word, you may only need to recognise it, not use it. That's a lighter entry.

Phrasal verbs deserve their own entries, because their meaning often has little to do with the individual words: give up, look after, put off. The phrasal verbs lesson shows how they work.

Turn the notebook into a review habit

A notebook only helps if you use it to practise recalling words. A few habits make that easy:

• Cover the right-hand side. Fold the page or use a card to hide the definition and examples, then try to explain each word from memory.
• Test the other way round. Read your definition and try to come up with the English word.
• Review on a schedule. Look at new words the next day, again after about a week, and again after about a month.
• Rewrite weak entries. If a word keeps slipping, add a new example that's more personal or more vivid.

Testing yourself feels harder than rereading, and that's the point: having to dig a word out of memory is what makes it stay.

Paper or app?

Paper is flexible and pleasant to write in, and the act of writing helps some people remember. Its limits show up after a few hundred words: entries are hard to search, you have to work out your own review schedule, and you can't hear how a word sounds.

An app can take care of the repetitive parts. In VocabNote, for example, you type a word and get a note with the pronunciation, part of speech, a definition, a translation into your language, example sentences and a learning tip. You can save it to your word list, search it later, hear it spoken and quiz yourself on it. You still choose which words matter and write your own sentences, and that thinking is what makes words stick.

Whichever you use, the rule is the same: fewer words, fuller entries, regular testing.

Recap

• Record six things per word: part of speech, pronunciation, definition, translation, examples and word partners.
• Pick one way to organise the notebook (by date, topic or source) and stick to it.
• Only write full entries for words you'll actually use.
• Mark each word's progress, and test yourself on a schedule instead of rereading.
