Morphology

pass + off

The particle verb 'pass off' conveys a sense of moving something 'off' or away from importance, which gives learners a partial clue from the constituents ('pass' = move/transfer, 'off' = away). However, the specific pragmatic sense of treating something as unimportant or presenting it falsely is idiomatic and not fully predictable from the literal meanings, so a B1 learner who only knows the base words may not reliably infer the exact meaning.

Etymology

Pass off here is like something leaving the body or a place and going 'off' into the air, often quietly and without notice. That's why it means 'to release' gas or a bad smell without anyone noticing.
