Here are some native-speaker expressions and similes for describing people.
A simile (pronounced “sim-i-lee”) is a type of comparison. You can make this comparision by saying “as + adjective + as + noun”.
There are many similes in English, but these ones are used particularly to describe people. You’ll hear them a lot in spoken English, and it’s also worth learning a couple of them to impress people in conversation!
