Husband has whisky after work -- it's child's play (9)
I believe the answer is:
hopscotch
'child's play' is the definition.
(I've seen this before)
'husband has whisky after work' is the wordplay.
I cannot really understand how this works, but
'husband' could be 'h' (abbreviation) and 'h' is found within the answer.
'whisky' could be 'scotch' (Scotch whisky is an example) and 'scotch' is found in the answer.
'work' could be 'op' (short for opus) and 'op' is found in the answer.
No letters remain.
This explanation may well be incorrect...
'it's' acts as a link.
Can you help me to learn more?
(Other definitions for hopscotch that I've seen before include "Jumping game" , "Children's pavement game" , "Traditional children's game" , "kids jump about in it" , "Playground game" .)
