Morphology

fast + one

The combination 'fast' (quick) + 'one' (a single act) gives a partial clue — it can suggest a quick action — but the specific sense 'a clever or deceitful trick' is idiomatic and not directly derivable from the literal words. Because the deceitful/clever nuance arises from usage (especially in 'pull a fast one') rather than pure composition, a B1 learner who only knows the constituents would only sometimes infer the correct meaning.

Etymology

Fast one comes from the idea of doing a quick move: the word fast means 'quick' and one means a single action, like a sudden trick. So it now means 'a clever or deceitful trick'.
