Entertainers turn on match (6,3)
I believe the answer is:
double act
'entertainers' is the definition.
I don't know anything about this answer so I can't judge whether it can be defined by this definition.
'turn on match' is the wordplay.
'turn' becomes 'act' (theatre).
'on' says to put letters next to each other.
'match' becomes 'double' (double can mean a match or copy).
'act' after 'double' is 'DOUBLE ACT'.
Can you help me to learn more?
(Other definitions for double act that I've seen before include "Partnership" , "Funny man and stooge, perhaps" , "Performance by a pair" , "Comic pair" , "What has four legs and makes us laugh" .)
