cuidar
/kwiˈdaɾ/ · A1 · verb
to look after, take care of
🏠 From Latin cogitare (to think): to care for something is to keep thinking of it
Cuidar comes from Latin cogitare, the root of English cogitate. Old Spanish cuidar meant to think; the sense shifted to giving something your attention, then to looking after it. Cuidado (careful!) is the same word: mind it.
