Morphology

fly + open

The meaning 'to open suddenly and quickly' is directly derivable from combining 'fly' (to move very quickly) with 'open' (become or make accessible): the verb conveys rapid motion and the complement names the resulting state. This resultative/compositional pattern is common cross-linguistically and follows a transparent motion + result structure that a B1 learner who knows both words would readily understand.

Etymology

The phrasal verb fly open comes from the image of something that seems to fly (move fast) into the open position, like a door blown by wind that suddenly swings wide. So it means 'open suddenly and quickly'.
