Morphology

in + passing

The meaning 'incidentally' or 'briefly' is directly recoverable from combining 'in' (marking manner/time) with 'passing' (brief, transient), so a B1 learner who knows both constituents can infer the MWE. This compositional pattern is cross-linguistically common (e.g. French 'en passant', Spanish 'de pasada') and follows straightforward English adjective + prepositional usage.

Etymology

In passing comes from the simple image of passing by someone or something: you do not stop, you only move past it. So when you mention something in passing, you say it quickly and only as a small, 'incidentally' comment.
