Morphology

slip + up

The verb 'slip' can already mean 'to make an error', and the particle 'up' here signals a completed or minor occurrence, so the meaning 'to make a careless or minor mistake' is directly derivable from the constituents. This verb + particle compositional pattern is common in English (and has parallels in other languages), so a B1 learner who knows the parts will likely understand the MWE.

Etymology

The phrasal verb slip up comes from the simple image of slip as sliding by accident and up as a sudden wrong move. Imagine stepping on a wet floor, suddenly sliding and making a small mistake, so slip up means 'to make a careless or minor mistake'.
