Morphology

stub + out

The software sense of 'stub out' (to replace or provide a temporary placeholder implementation) is a specialized technical meaning that cannot be inferred from the literal verb 'stub' (to extinguish a cigarette) plus 'out'. The MWE derives from programming jargon (noun 'stub' = placeholder) and is not a transparent compositional extension of the given constituent senses, so a B1 learner knowing the literal words would not predict this meaning.

Etymology

Stub out in programming comes from making a short, simple piece of code called a stub that stands in for the real function while you test. So, to stub out something in code means 'to replace it temporarily with a simple fake'.
