Reportedly lines up to get signals (4)
I believe the answer is:
cues
'signals' is the definition.
(I've seen this in another clue)
'reportedly lines up' is the wordplay.
'reportedly' shows a homophone (sound like).
'lines up' becomes 'queues' ('queue' can be a synonym of 'line up').
'queues' sounds like 'CUES'.
'to get' is the link.
(Other definitions for cues that I've seen before include "Prompts for action" , "Actors' signals" , "Actor's signal" , "Snooker ball strikers" , "Signals for action" .)
