Did you know?

We'll break it to you gently: abrupt derives from abruptus, the past participle of the Latin verb abrumpere, meaning "to break off." Abrumpere combines the prefix ab- with rumpere, which means "to break" and which forms the basis for several other words in English that suggest a kind of breaking, such as interrupt, rupture, and bankrupt. Whether being used to describe a style of speaking that seems rudely short (as in "gave an abrupt answer"), something with a severe rise or drop ("abrupt temperature change"), or something that seems rash and unprecipitated ("made the abrupt decision to quit college"), abrupt, which first appeared in English in the 16th century, implies a kind of jarring unexpectedness that catches people off guard.

Etymology

from Latin abruptus "abrupt," derived from abrumpere "to break off," from ab- "from" and rumpere "to break" — related to corrupt, interrupt, rupture

Word Origin
If a person is rudely brief in speech or manner or stops you before you finish talking, you could say that that person is abrupt. If a road ends suddenly, you could say that the road comes to an abrupt end. In both of these cases you might think of something that is abrupt as "breaking off." Abrupt comes from the Latin word abruptus, meaning "broken off, ending suddenly." That word is formed (with the addition of the prefix ab-, meaning "from") from the Latin word rumpere, meaning "to break." Latin rumpere has given us several other English words that carry the idea of breaking: interrupt, rupture, and corrupt.
