Morphology

turn + signal

The meaning 'a blinking light indicating direction' is directly and transparently built from 'turn' (an act of turning) combined with 'signal' (an indication). This noun+noun composition mirrors common cross-linguistic patterns (e.g. Spanish 'señal de giro') so a B1 learner who knows both constituents will readily infer the MWE meaning.

Etymology

Turn signal comes from the simple idea of a turn and a signal. Long ago drivers used hand signals or a small arm on the car to show which way they would go, and later a blinking light did the same job, so today a turn signal is the light that tells other drivers your direction.
