Morphology

flag + signal

The meaning 'a method of sending messages by displaying or moving flags' is directly and compositionally derivable from 'flag' (a piece of cloth) + 'signal' (a cue or gesture). This noun–noun combination follows a common pattern (a signal made with a flag) and is cross-linguistically transparent (e.g., semaphore equivalents), so a B1 learner who knows both words would readily infer the meaning.

Etymology

Flag signal comes from the simple image of a bright flag shown or waved to make a signal so people far away could 'receive a message'. That's why a flag signal means a message sent by showing or moving flags.
