Morphology

abrupt = ab + rupt

Although historically analyzable as ab- + rupt, 'rupt' is not a standalone English word and the meaning is not transparently recoverable by an average B1 learner.

Etymology

Abrupt comes from ab- ('away') and rupt ('break'), like land that looks 'broken off' from the ground. That image explains why abrupt can describe a very steep or sudden drop.
