Adjectives can be used to describe lots of things, from physical size, age, shape, colour, material, to more abstract things like opinion, origin and purpose.

We can use adjectives together to give a detailed description of something.

Adjectives that express opinions usually come before all others, but it can sometimes depend on what exactly you want to emphasise.
