How to improve vocabulary comes down to meeting new words often, writing them down with an example, using them yourself within a day or two, and reviewing them at spaced intervals. Fifteen focused minutes a day beat one long session a week. Below you will find seven habits, a seven-day plan, a notebook template and a simple way to avoid sounding stiff.
In brief:
- Read a little every day and note words you meet in context.
- Write a short example sentence of your own for each new word.
- Use each word aloud or in writing within a day or two.
- Review in short sessions spread over several days, not in one marathon.
- A rich vocabulary means the right word, not the biggest word.

What vocabulary is, and why "knowing" a word is not enough
Linguists split vocabulary into two parts. The active (or productive) vocabulary is the words you use yourself in speech and writing. The passive (or receptive) vocabulary is the words you recognize when you hear or read them but rarely use (Wikipedia, "Vocabulary"). For most people the passive part is the larger one, which explains the familiar feeling of having a word "on the tip of the tongue".
That is good news. You do not have to learn thousands of brand-new words. A large part of the work is moving words you half-know from the passive side to the active side. The same source notes that vocabulary keeps changing across life through direct instruction, independent reading and everyday exposure to language, so it is never too late to start.
How to improve vocabulary: 7 habits that work
The advice of university language centres is consistent: read widely, look words up, keep a notebook, study a little each day and use what you learn. Our communication book (more on it below) has a chapter on vocabulary that lists similar habits. Here they are in one plan.
- Read every day, with a purpose. RMIT University's study-skills blog suggests reading slowly and looking up unfamiliar words, across fiction, non-fiction and classics. Pick something you enjoy, because you will keep going. When you hit an unknown word, first guess its meaning from the sentence, then check.
- Keep a notebook and review it each week. Note the word, its meaning, one example and where you met it. Review the page at the end of the week. A plain list is not enough: the University of Lorraine's language-learning centre says lists are useful but not sufficient and advises grouping words by theme or context.
- Collect two or three synonyms a day. For a word you use all the time ("good", "important", "problem"), look up a few alternatives in a thesaurus and note how they differ. This is how you gain precision, not just volume.
- Look at where a word comes from. RMIT also recommends studying word roots, including Latin and Greek origins, prefixes and suffixes. One short etymology a day makes new words easier to remember and to guess.
- Listen when your hands are busy. Audiobooks and podcasts turn commutes and chores into practice. RMIT notes that audio also shows you how a word is pronounced and used in context.
- Read aloud and write short summaries. Reading aloud puts words in your mouth; summarizing an article or a film in a few lines forces you to choose your own words. Both move vocabulary from passive to active.
- Play with words. Crosswords, word searches, Scrabble and flashcard apps are all on RMIT's list. They are not a replacement for reading, but they keep the habit light.
The missing step: use the word within a day or two
Recognizing a word is not the same as having it available when you talk. The step most people skip is production: using the new word in a sentence of their own.
A simple notebook layout makes this almost automatic:
| Word | Meaning in my own words | My sentence | Where I met it | Used on |
|---|---|---|---|---|
| meticulous | very careful about details | "She keeps meticulous notes." | a newspaper article | Tuesday, in an email |
| to defuse | to calm a tense situation | "A joke defused the argument." | a podcast | Wednesday, in a talk |
| nuance | a small but important difference | "There is some nuance in this case." | a novel | Friday, in a chat |
The last column is the one that matters. If it is still empty after two days, say the sentence aloud, send it in a message, or use it in a quick note to yourself. The University of Lorraine's centre recommends repeating in short sessions rather than all at once and puts it plainly: 20 minutes a day is better than three hours a week.
A 7-day plan: 15 minutes a day
RMIT's advice is to set a goal, a schedule and to stick to about 15 minutes a day. Here is one way to spend them:
| Day | 15-minute task |
|---|---|
| Monday | Read an article; mark 5 unknown words; write them in the notebook with a meaning |
| Tuesday | Write your own sentence for each of the 5 words; say them aloud |
| Wednesday | Look up 2-3 synonyms for a word you overuse |
| Thursday | Listen to a podcast or audiobook chapter; note 3 words |
| Friday | Write a five-line summary of what you read or heard, using at least 3 new words |
| Saturday | Play a word game or do a crossword; add any new words |
| Sunday | Review the notebook page; test yourself without looking; keep the words you missed for next week |
After a week, repeat with new material. Keep the words you missed on the list. RMIT also suggests checking after a week whether you still remember your word lists, which is exactly what Sunday does.
A rich vocabulary is not the same as big words
It is tempting to chase long or rare words. That can backfire. RMIT's own advice includes a caution to avoid very rare or highly specialized words when talking with children, friends or family. The goal is to be understood and to be precise.
In our communication book, the chapter on fluent speaking recommends simple words over big ones, and the one on charisma lists simple language among its tips. So a better question than "Is this word impressive?" is "Does this word say exactly what I mean, in a way my listener understands?"
What our book adds (available in Spanish)
Our communication book has no English edition. The edition shown here is the Spanish one, Lenguaje Corporal, Comunicación Persuasiva y Retórica by Mateo Nevarez, so it suits you if you read Spanish or are learning it. The other editions are in French and German; the German title is literally about improving expression and expanding vocabulary.
Chapter 5 gives 11 ways to expand your vocabulary and 13 tips for speaking more expressively. Among them: a reading routine, a notebook of looked-up words reviewed weekly, two or three synonyms a day, one etymology a day, audiobooks during idle time, reading aloud, writing summaries, word apps and crosswords. For speaking, it suggests opening with a simple thesis or a 30-second summary, varying your pace, keeping pauses short and defining jargon. The exercises include recording yourself, practicing in front of a mirror and asking friends how natural you sounded.
It is a practical handbook, not a word list or a grammar book, and it does not give study references. Use it for the habits and the exercises, and use a dictionary and your own notebook for the words themselves. There is also an audiobook in Spanish.

When to ask a professional
Everyone loses a word now and then. If you notice a sudden change in how you speak or find words, such as slurred speech, repeatedly mixing up words or trouble understanding others, talk to a doctor promptly. If reading or spelling has always been very hard for you or your child, a teacher or a speech-language professional can assess whether specific support would help. This article is general guidance for everyday communication, not a diagnosis.
Frequently asked questions about how to improve vocabulary
How many new words should I learn a day?
Start small. RMIT mentions a word-a-day email as an easy way in, and a few words a day that you actually use is better than twenty you forget. The aim is words you can use, not a score.
Is reading really the best way?
Reading is the most common advice, because you meet words in context and in different forms. It works best when you add a notebook and some active use, because reading alone can leave words on the passive side.
Are vocabulary apps worth using?
They can help as a light daily habit, especially for review and flashcards. Pick one that lets you add your own example sentences, and still read and speak outside the app.
How long until I notice a difference?
It varies from person to person, and nobody can promise a timetable. Many people notice that words come more easily after a few weeks of regular practice, but that depends on how often you use them.
Should I learn word lists?
A list can be a first step, but on its own it is not enough. Group words by theme, add an example, and use them in real sentences, as the University of Lorraine's centre advises.
How do I avoid sounding pretentious?
Choose the word that fits your listener and your meaning. Save rare words for writing, where there is time to check them, and prefer plain words in conversation.
