Present means here or now, or a gift, or to show and introduce. Prevent means to stop something happening. Everyone was present; present the award; prevent the leak. A single letter separates a word about being there from a word about stopping.
The core difference
- present — adjective: here, existing now. Those present, the present owner. Noun: a gift; the current time. A birthday present, at present. Verb: to give or show formally. Present the findings, present a cheque.
- prevent — verb: to stop from happening or from doing. Prevent accidents, nothing could prevent her leaving.
The tell
Prevent is only ever a verb, and it always has something being stopped. Its family is prevention and preventive. Present is three words in one, and its families are presence, presentation and presenter. Stress helps with the verb: PRES-ent for the adjective and noun, pre-SENT for the verb — while prevent is always pre-VENT.
In use
- present — All members were present. He presented the award himself.
- prevent — Vaccines prevent disease. Nothing could prevent the leak.
Common slips
- to present further damage → to prevent further damage
- everyone was prevent at the meeting → everyone was present at the meeting
Prevention prevents; presence is present.
Where the words come from
Present is from Latin praesens, "being before, at hand" — prae- plus esse "to be". Prevent is from Latin praevenire, "to come before" — prae- plus venire "to come". It first meant to anticipate or act ahead of, which is how the Book of Common Prayer uses it; the modern "stop" sense grew out of getting there first.
