Theatrical people having a fling? (4)
I believe the answer is:
cast
'fling?' is the definition.
(I've seen this before)
'theatrical people having a' is the wordplay.
I cannot really see how this works, but
'a' is within the answer.
The remaining letters 'cst' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for cast that I've seen before include "Provided players" , "Throw - actors - shape something - burrowing worm's sand" , "Allot parts in film, play" , "Character" , "discarded" .)
