What does babysit mean?
To babysit is to look after a child or children for a limited period, usually while their parents are out at work or socialising, often in exchange for payment. The word is chiefly used as a verb, though it also functions informally as a noun meaning such a job or occasion. First appearing in mid-twentieth-century American English as a shortened form of 'babysitter', it quickly spread throughout the English-speaking world and became the standard everyday term for casual child care. Beyond its literal sense, babysit has developed a playful figurative use: people say they are 'babysitting' colleagues, interns, or even temperamental machinery when they feel they are merely supervising rather than doing substantive work. This secondary usage carries a mildly sarcastic tone, implying that the task requires patience rather than skill. Simple, familiar, and universally understood, babysit remains one of the most recognisable terms in modern family life.
To look after children temporarily while their parents are away.
"He babysits for his sister most weekends."
Often used with 'for' to indicate whose children are being cared for.
(Informal) A job or occasion of looking after children in this way.
"She earns extra money doing evening babysits around the neighbourhood."
Despite its name, 'babysit' wasn't coined by parents — it's a back-formation invented in the 1940s America by trimming 'babysitter' down to size.

Etymology of babysit
Babysit originated in the United States during the 1940s as a back-formation from 'babysitter', itself a compound of 'baby' and 'sitter'. Rather than deriving from older roots, the word was created by lopping the '-er' off the agent noun to produce a convenient verb form. Its success spawned later imitations such as 'housesit' and 'petsit', which borrowed the same pattern for other kinds of care-taking.
