Straighten a queue, reportedly (5)
I believe the answer is:
align
'straighten' is the definition.
(I've seen this before)
'a queue reportedly' is the wordplay.
'queue' becomes 'line' (a line of people).
'reportedly' shows a homophone (sound like).
'line' sounds like 'lign'.
'a'+'lign'='ALIGN'
(Other definitions for align that I've seen before include "Arrange so as to be parallel" , "Place in a row" , "Bring (things) into a proper relationship" , "Get straight" , "Put into a straight row" .)
