Morphology

blow + off

The sense 'to deliberately ignore or avoid' is not directly derivable from the literal meanings of 'blow' (move air/strike) + 'off' (away), so a learner who only knows the constituents would not reliably infer 'ignore'. However, because English phrasal verbs with 'off' often convey removal or dismissal, learners might plausibly guess a dismissive sense; this partial predictability makes the item only semi-transparent.

Etymology

Blow off comes from the image of a strong wind or an explosion that blows something off a surface, like a lid or roof tile being carried away. That's why it means 'to become detached and carried away by a strong force'.
