Smart Tips
Use your hands! English speakers often use gestures while saying 'big' or 'small' to show exactly what they mean.
Use 'okay' or 'not bad'. It's a safe middle ground.
Check your adjective for an 's'. If you see one, delete it!
Remember that 'big' can describe events, not just objects.
发音
Big
Short 'i' sound like 'sit'. Do not say 'beeg'.
Good
The 'oo' is short, like in 'foot'. Not long like 'food'.
Bad
The 'a' is wide, like in 'cat'.
Small
The 'a' sounds like 'aw' in 'law'. The 'l' is a 'dark l'.
Emphasis
It is a BIG dog.
Stressing the adjective adds extra emotion or surprise.

Yes! You can use `very` before any of these adjectives to make them stronger, like `very good` or `very small`.
They are mostly the same. `Big` is more common in daily speech, while `large` is a bit more formal.
Usually, yes. However, in some very old slang, it could mean 'cool', but you should always use it as a negative word at the A0 level.
You say `a good` because 'good' starts with a consonant sound. You only use `an` if the next word starts with a vowel sound.
Yes, but be careful. `A big man` usually means he is wide or strong. If you mean he is tall, use the word `tall`.
In modern English, especially in the US, `I am good` is the standard response to 'How are you?'. `I am well` is more formal.
Yes! Just remember the adjective doesn't change. `Big dogs`, `small cats`, `good books`.
Yes, they are very similar. `Small` is more about the actual size, while `little` can sound more cute or emotional.
