Plays in the Proms? (5)
I believe the answer is:
romps
'plays in the proms?' is the definition.
'romps' can be an answer for 'plays' ('romp' can be a synonym of 'play'). I am not certain of the 'in the proms?' bit.
'plays in the proms?' is the wordplay.
'plays in' indicates anagramming the letters (I've seen 'playing in' mean this (I've seen this in other clues)).
'proms' is an anagram of 'ROMPS'.
Can you help me to learn more?
(Another definition for romps that I've seen is " Frolics".)
