Words that describe a person or a thing (big, red, expensive, interesting) are called adjectives. In English, they follow two simple rules.
1. They never take an -s
The word stays the same, for one thing or for many. Only the thing itself takes the -s.
- a big house → two big houses
- an old friend → my old friends
- This shoe is expensive. → These shoes are expensive.
2. They come before the thing they describe
- a red car
- an interesting book
- a small flat in the city centre
After be, look, seem or feel, they come at the end, still with no -s:
- The cars are red.
- Your children look tired.
3. Nationalities too
Nationalities follow the same rules, and they always start with a capital letter.
- two Italian restaurants
- my Spanish colleagues
