When father gets his recreation (7)
I believe the answer is:
pastime
'recreation' is the definition.
(I know that pastime is a type of recreation)
'when father gets his' is the wordplay.
I cannot quite understand how this works, but
'when' could be 'e' (I've seen this in other clues) and 'e' is located in the answer.
'father' could be 'pa' (pa can mean dad or father) and 'pa' is located in the answer.
The remaining letters 'stim' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for pastime that I've seen before include "diversion" , "doing the crossword, say" , "relaxation" , "Hobby; regular activity" , "Leisure pursuit" .)
