Attractive guy perhaps had been a lady’s kitchen helper (10)
I believe the answer is:
dishwasher
'kitchen helper' is the definition.
(I've seen this before)
'attractive guy perhaps had been a lady's' is the wordplay.
I cannot really understand how this works, but
'had' could be 'd' (in contractions e.g. 'I'd', 'you'd' etc) and 'd' is found within the answer.
'been' could be 'was' (being is a kind of being) and 'was' is located in the answer.
'lady's' could be 'her' (belonging to a lady) and 'her' is found within the answer.
The remaining letters 'ish' 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 dishwasher that I've seen before include "Kitchen item" , "kitchen helper" , "Kitchen machine" , "Appliance for cleaning plates, cutlery etc" , "cleaner" .)
