Etymology

Origin of trait

First recorded in 1470–80; from Middle French: literally, “something drawn,” from Latin tractus; see tract ¹

Explanation

A trait is something about you that makes you "you." When your mother says that you get all your best traits from her, she means you have the same charming smile and the same brilliant mind as she has. In science, trait refers to a characteristic that is caused by genetics. Having green eyes or being shorter than average are traits a person might have. In more general use, a trait is an important part of someone’s personality or appearance. Try to describe your favorite teacher in three words and you’ll probably come up with a list of her essential traits — such as compassionate, calm, and kooky.
