Other forms: kept, keeping, keeps
Keep is to go on having something instead of handing it over. You keep the change, keep your old school photos, keep the receipt in case the shoes do not fit.
From there it spreads everywhere. Keep plus -ing means carry on: keep walking, keep trying, keep asking until someone answers — and never keep to walk. Keep also puts something in a state and holds it there: keep the door open, keep the soup warm, keep quiet, keep someone waiting. It covers storing and looking after — she keeps the spare key under the pot, they keep chickens, he keeps a diary — and promises: you keep a promise, keep a secret, keep an appointment. The past is kept, kept, which surprises learners the first time. A castle keep, the strong tower at the centre, is the same word: the part that holds out.

Old English cēpan meant to seize, hold and observe, and Middle English kepen meant to guard, look after and watch. Behind them stands Proto-Germanic *kōpijaną, "to look, heed, watch, observe", from a Proto-Indo-European root *ǵāb-, "to look after". The oldest sense is watching over something rather than owning it — still there when you keep a secret or keep an eye on the pan.

Built from
From Middle English kepen (“to keep, guard, look after, watch”), from Old English cēpan (“to seize, hold, observe”), from Proto-West Germanic kōpijan, from Proto-Germanic kōpijaną (“to look, heed, watch, observe”) (compare West Frisian kypje (“to look”)), from Proto-Indo-European ǵab-, ǵāb- (“to look after”) (compare Lithuanian žẽbti (“to eat reluctantly”), Russian забо́та (“care, worry”)). The dialectal keep may be analyzed as a semantic loan from a local language—compare cadw and cmn 收.
