Choosing between big · large · great

Big is the everyday word for size and also for importance: a big house, a big decision. Large is slightly more formal and is used mainly for size and amount; for importance, big is the usual word: a large amount, a large family, a large number. Great is used for size mainly in formal or literary writing (a great oak); in ordinary speech it means very good (a great idea) or very important (a great leader), and with feelings and uncountable nouns it means a lot of: great difficulty, great care.

Usage

In speech big is used like an adverb in a few phrases: think big, win big, make it big. In careful writing, large is often preferred for amounts and numbers: a large amount of money, a large number of people; a big increase is normal.

Common mistakes

a big number of people a large number of people
With number, amount, and quantity, large is the usual choice.
There was a big rain last night. There was heavy rain last night.
Rain, snow, and traffic are usually heavy, not big; wind is usually strong.

For translators

Meaning across languages Big covers physical size and importance; many languages use different words. For amounts and numbers English prefers large, and for weather heavy. Big brother and big sister, meaning an older sibling rather than a tall or fat one, are a separate word in many languages.
Grammar trap The comparative and superlative double the g: bigger, biggest. Big is used both before a noun and after be.
Pronunciation trap The vowel is the short i of sit, and the final g is a full g sound with no vowel after it; it must not become k.
