Cleaning it is a bit of work for a woman (5)
I believe the answer is:
floor
'cleaning it' is the definition.
I can't judge whether this definition defines the answer.
'is a bit of work for a woman' is the wordplay.
'is a bit of work' becomes 'or' (I can't explain this - if you can you should give a lot more credence to this answer).
'for' means one lot of letters go next to another (I've seen this in other clues).
'a woman' becomes 'Flo'.
'or' put after 'flo' is 'FLOOR'.
Can you help me to learn more?
(Other definitions for floor that I've seen before include "Part of building" , "Inside horizontal surface" , "Puzzle" , "at bottom of forest" , "Knock down; storey" .)
