Vocabulary
Build your English vocabulary
A bigger vocabulary is not about long words. It is about having the right word ready when you need it.
Your vocabulary is every word you know well enough to use, not just recognise.
That difference matters. Most people recognise three or four times more words than they actually use. Growing your vocabulary mostly means moving words from the first group into the second.
Long words are not better words
Beginners often think a big vocabulary means using words like utilise and commence. Skilled writers do the opposite. They use the shortest word that is exactly right.
We will commence the utilisation of the new system.
We will start using the new system.
The second one is shorter, clearer, and sounds more confident. Long words hide meaning, they do not add it.
Where a strong vocabulary actually helps
The real gain is precision. Instead of stacking "very" in front of a weak word, you reach for one word that carries the whole meaning.
very tired → exhausted
very hungry → starving
very important → crucial
very happy → delighted
The checker on this site flags "very" plus an adjective and offers you the single word instead.
Synonyms and antonyms
- Synonym.
- a word that means nearly the same thing. Big and large.
- Antonym.
- a word that means the opposite. Big and small.
Here is the part most word lists leave out: synonyms are rarely identical. Slim, thin and skinny all describe the same body, but one is a compliment, one is neutral, and one is usually rude. Choosing between synonyms is choosing a feeling, not just a word.
Words that sound alike but are not the same
These cause more written mistakes than any other part of vocabulary, because your ear cannot tell them apart.
Incorrect: He gave me some good advise.
Correct: He gave me some good advice.
Advice with a c is the thing you get, and it rhymes with "ice". Advise with an s is the action, and it rhymes with "wise".
Incorrect: I want to loose weight.
Correct: I want to lose weight.
Lose with one o is the verb. Loose with two o rhymes with "goose" and means not tight.
Words you cannot count
Some English nouns name a mass rather than separate items. They take no "a" and no plural s. This trips up almost every learner.
Incorrect: He gave me an advice and many informations.
Correct: He gave me some advice and a lot of information.
To count them, use a measure word: "two pieces of advice", "three items of luggage".
How to actually grow your vocabulary
- Read slightly above your level. If you know every word, you are not learning any.
- Learn words in sentences, not in lists. A word on its own has no shape. A word in a sentence shows you how it behaves.
- Write the new word within a day. Recognising a word is not knowing it. Using it once is what moves it across.
- Space out your reviews. Reviewing on day one, day three and day seven beats reviewing three times in one evening.

Questions people ask
How many words do I need to know in English?
Around 2,000 to 3,000 common words cover most everyday conversation. Comfortable reading of newspapers and books usually needs closer to 8,000. Knowing more words matters less than knowing common words well.
What is the difference between a synonym and an antonym?
A synonym means nearly the same thing, like big and large. An antonym means the opposite, like big and small. Synonyms are rarely identical, so the one you pick changes the feeling of the sentence.
Is it better to use long words in writing?
No. Skilled writers use the shortest word that is exactly right. Long words usually hide meaning rather than add it. Replace very plus an adjective with one precise word instead.
How do I stop confusing words like advice and advise?
Use the sound. Advice rhymes with ice and is the thing you get. Advise rhymes with wise and is the action. Most confusable pairs have a test like this.
