Why Learn Idioms for Describing Personality?
Idioms and expressions make English more vivid and natural. If you only use basic adjectives such as nice, lazy, friendly or hard-working, your vocabulary may sometimes sound repetitive.
By learning idioms to describe personality and character, you can express more specific ideas and understand how native speakers describe people's behaviour in everyday English.
For example, instead of saying that someone is very ambitious and determined, you can describe them as a go-getter. Instead of saying that someone is very practical and sensible, you can call them down-to-earth.
This is one reason why learning common English idioms is useful for learners who want to develop a more natural and expressive vocabulary.
