Definition
To keep something is to go on having it — the plainest, widest word for not letting go. It comes from Old English cēpan, 'to seize, hold, observe', and it has kept that open reach: you keep a promise, a secret, a seat, a pet, your temper. Unlike retain, which holds on deliberately against the chance of loss, keep can be effortless and ordinary. Its true opposite is to abandon — to set a thing down and walk away from it for good.
Examples
- It takes real effort to keep your composure when everyone around you is starting to panic.
- Careful notes help you keep facts that you would otherwise lose within a week.
- They chose to keep the family house long after it would have been easier to abandon it.
