Value in working with valid variety performer (12)
I believe the answer is:
vaudevillian
'variety performer' is the definition.
'vaudevillian' can be an answer for 'performer' (vaudevillian is a kind of performer). I'm not sure about the 'variety' bit.
'value in working with valid' is the wordplay.
'working with' is an anagram indicator (working with the letters).
'value'+'in'='valuein'
'valuein' anagrammed with 'valid' can make 'VAUDEVILLIAN'.
Can you help me to learn more?
(Another definition for vaudevillian that I've seen is " Light entertainer".)
