Hard to tolerate rather dirty husband squeezing out KY (1,3,4)
I believe the answer is:
a bit much
'hard' is the definition.
Both the definition and answer are adjectives. Maybe you can see a link between them that I can't see?
'tolerate rather dirty husband squeezing out ky' is the wordplay.
I cannot quite see how this works, but
'rather' could be 'abit' ('a bit' can mean rather or to some extent) and 'abit' is present in the answer.
'husband' could be 'h' (abbreviation) and 'h' is located in the answer.
This may be the basis of the clue (or it may be nonsense).
'to' is the link.
Can you help me to learn more?
(Other definitions for a bit much that I've seen before include "unacceptable" , "Too much to put up with, unreasonable" , "out of order" , "That's not on" , "Taking liberties" .)
