Doing someone a good turn (12)
I believe the answer is:
entertaining
'doing' is the definition.
The definition and answer can be both to do with social activities as well as being present participle verbs.
Perhaps you can see an association between them that I don't see?
'someone a good turn' is the wordplay.
I cannot really understand how this works, but
'a' is present in the answer.
'good' could be 'g' (abbreviation) and 'g' is present in the answer.
'turn' could be 't' (abbreviation in Oxford Dictionary of Abbreviations) and 't' is found within the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for entertaining that I've seen before include "At home" , "Comical" , "Recreational" , "creating a diversion" , "fun" .)
