It is paid for what baby-minders do after six (5)
I believe the answer is:
visit
'do after six' is the definition.
'visit' can be an answer for 'do' (thesaurus). I am not sure about the 'after six' bit.
'it is paid for what baby-minders' is the wordplay.
I cannot quite understand how this works, but
'it' could be 't' (abbreviation. e.g. in 'tis) and 't' is located in the answer.
'is' is within 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 visit that I've seen before include "Call on - stay" , "Call in to see, socially or on business" , "Call on (someone)" , "Come to see" , "Call upon" .)
