means A person, often registered and trained, who looks after other people's children, usually in their own home, in exchange for payment.

from A transparent compound of 'child' plus 'minder' — from the verb 'to mind,' meaning to watch over or take care of, a sense of the word that's been around since Old English 'myndian.' 'Minder' itself emerged as agent-noun shorthand for someone who looks after a person or thing; 'childminder' crystallized as its own job title mainly in 20th-century Britain, where it became the formal term for home-based, paid child care as distinct from nurseries or babysitters.
