Babysuit

Part of speech: noun

Definitions

1. A one-piece outfit for babies that covers the body from the shoulders down to the feet and fastens for easy changing
2. A snug all-in-one garment worn by infants, combining a top and trousers into a single piece of clothing
3. An infant's close-fitting one-piece clothing, often with snap fasteners at the crotch, designed for sleeping or everyday wear

Etymology: Babysuit is a plain compound: "baby" joined to "suit," with "suit" in its older sense of a set of matching garments worn together. A one-piece garment for infants came to be called a babysuit, and the word is built transparently from its two parts with no older history behind it. The word is a modern formation, so there is no earlier sense to trace. Its meaning matches the garment it names: a single piece covering a baby's torso and legs, usually fastened at the crotch, and a "suit" in the sense of an outfit made to be worn as one unit.

Synonyms: romper, onesie, sleepsuit, babygro
