Morphology

foul + up

There is a transparent link between 'foul' (to make dirty/contaminate) and the idea of ruining or making a mess, while the particle 'up' commonly marks completion or a resultant state, so a learner could partially infer the sense 'mess up/ruin'. However, the specific extension to 'make a mistake' or 'botch' is somewhat idiomatic and not entirely predictable from the parts alone, so full comprehension without prior exposure is uncertain.

Etymology

Foul up comes from old sailors. When a rope got tangled they called it fouled, and a tangled rope could stop the whole job, so to foul up came to mean 'to make a mistake' or 'ruin something'.
