Synonym discussion
Sense: noun/2
All four words describe something that conveys information, but they differ in timing and purpose. A 'cue' is specifically something that tells you to start an action — it has a triggering function. A 'signal' is the closest synonym and can be used almost interchangeably, though 'signal' often implies a deliberate sign (a whistle, a waved flag) whereas a 'cue' can be accidental. A 'sign' is broader: it can be any piece of evidence or marker (dark clouds are a sign of rain, but not a cue to act). A 'prompt' focuses on reminding someone of what to say next, especially in performance or conversation. An 'indication' is the weakest and most general — it suggests something is likely true but does not necessarily demand action. Example: 'The applause was a cue for the singer to return to the stage.' Here, 'cue' is the best choice because the applause pushes the singer to act. A 'signal' would also work, but 'sign' or 'indication' would sound too passive.

Etymology
The word 'cue' in its theatre sense (16th century) may come from the letter 'Q', used in old play scripts as a short form of Latin 'quando' meaning 'when' — it marked the moment an actor should speak. The billiards sense (18th century) has a separate origin: it comes from French 'queue' meaning 'tail', because the stick resembles a tail. Both words arrived in English at different times and through different routes, but they are now spelled the same way.
