Morphology

smoke + signal

The meaning 'a method of sending messages using patterned puffs of smoke' is directly and transparently derivable from combining 'smoke' (visible plume from combustion) with 'signal' (a cue used to communicate). This straightforward noun+noun composition is cross-linguistically common, so a B1 learner who knows both constituents would readily infer the MWE's meaning.

Etymology

Smoke signal comes from the old way of making short puffs or a steady column of smoke in a clear pattern to act as a signal people far away could see and understand. So today a 'smoke signal' means a visible 'message' or a sign for 'help'.
