Argument over key work's exploitation of ambiguity (8)
I believe the answer is:
wordplay
'exploitation of ambiguity' is the definition.
The answer and definition can be both related to communication as well as being singular nouns.
Perhaps there's a link between them I don't understand?
'argument over key work's' is the wordplay.
I cannot quite see how this works, but
'over' could be 'o' (cricket abbreviation) and 'o' is found within the answer.
'key' could be 'd' (musical key) and 'd' is found within the answer.
'work' could be 'play' (dramatic work) and 'play' is found in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for wordplay that I've seen before include "pun?" , "Puns etc" , "Wit" , "Punning" , "Making puns" .)
