Morphology

slip + through

The core meaning 'to pass easily or quickly through' is directly compositional from 'slip' (to move smoothly/quietly) + 'through' (from one side to the other), so a B1 learner who knows the parts can infer the physical sense. The extended sense 'escape notice or be overlooked' is a straightforward metaphorical extension of that physical image (slipping through unnoticed) and is cross-linguistically common, so it remains predictable rather than idiomatic.

Etymology

Slip through comes from the picture of something small sliding out of your hand or through a narrow gap, like a coin that slips through your fingers. So it now means 'to escape', 'to be missed', or 'to be forgotten', as when a chance or a detail quietly 'slips through' without you noticing.
