What Does definition of kid Mean?
The definition of kid typically refers to a young human child, usually a toddler or school-age youngster. That is the sense most people use in everyday speech, like saying I have two kids or The kids are playing outside.
Kid can also mean a juvenile goat in agricultural contexts. Farmers and naturalists use that meaning in quite a literal way. And then there is the slang sense, where kid becomes a verb or a playful noun meaning to tease or to be playful with someone.
Etymology and Origin of definition of kid
The word kid comes from Old Norse kið, and it originally referred to a young goat. English borrowed and kept that original animal sense for centuries. Over time, the meaning widened and shifted to include human children as a familiar, informal term.
By the 16th and 17th centuries, writers in English were using kid to refer to both goats and children. The crossover probably reflects how people often name human offspring after animal young in many languages, a kind of affectionate shorthand.
