"Short" describes small measurement in length or time; "brief" describes short duration more formally.
Side-by-side comparison
Of little height, length, or duration. Broad, applies to objects, people, time, and texts.
She has short hair now, she cut it all off last week.
The meeting was short. We finished in 15 minutes.
He is too short to reach the top shelf.
Of short duration, concise. More formal. Only describes time or texts, not people or physical objects.
I will make this brief, we have a lot to cover.
She gave a brief but powerful speech at the opening.
In brief, the project was a success.
Common mistake
- •"He is brief" in English does not mean he is short in height, it means he is concise.
- •For height use "short." "Brief" only applies to time, speeches, texts, or visits, it never describes people physically or physical objects.
Trick to remember it
- •Can you measure it with a ruler, or is it a person's height? "Short." Is it the duration of an event or length of a text? "Brief" (more formal) or "short" (both work).
- •"Brief" NEVER describes people physically or physical objects.
Quick rule
- •"Short" = short in size, time, or height.
- •"Brief" = brief in time or length (events or texts only, more formal).
Did you know?
"In brief" and "in short" are nearly synonymous as summary connectors: both are equally correct and natural for wrapping up a point. But BRIEF has an interesting life as a noun: "a brief" in legal context is a written summary of legal arguments. "Briefing" is an informational session. "Briefs" are close-fitting underwear (because they are short). And "to brief someone" means to inform them concisely. SHORTS (short trousers) comes from SHORT, not BRIEF: the trousers are "short" in length, not "brief" in duration.
