Morphology

signal + flag

The meaning is directly derivable from combining 'signal' (something that conveys a cue) with 'flag' (a piece of cloth): together they denote a flag used to send signals or messages. This straightforward noun–noun composition is common cross-linguistically and follows standard English modification patterns, so a B1 learner who knows both constituents will understand it.

Etymology

Signal flag comes from sailors who used a bright piece of cloth, a flag, to give a signal to other ships by holding it up or waving it. So, that's why signal flag means 'a piece of fabric used to send messages' today.
