Entertainment shows gun users regularly ignored (6)
I believe the answer is:
revues
'entertainment shows' is the definition.
'revues' can be an answer for 'shows' (revue is a kind of show). I'm unsure of the 'entertainment' bit.
'gun users regularly ignored' is the wordplay.
'gun' becomes 'rev' (as in gunning or revving up a car engine).
'regularly ignored' indicates alternate letters (letters removed at regular intervals).
The alternating letters of 'users' are 'ues'.
'rev'+'ues'='REVUES'
Can you help me to learn more?
(Other definitions for revues that I've seen before include "Entertainments including song, dance and comedy" , "Entertainments with sketches and songs" , "Variety shows" , "Theatrical productions" .)
