Do the dirty on some woman for preference (6)
I believe the answer is:
rather
'for preference' is the definition.
(I've seen this before)
'do the dirty on some woman' is the wordplay.
I cannot really understand how this works, but
'the' could be 't' (the is pronounced as a 't' sound in some dialects) and 't' is present in the answer.
'some' could be 'a' and 'a' is found in the answer.
'woman' could be 'her' (her refers to a woman) and 'her' is located in the answer.
A single letter 'r' remains which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for rather that I've seen before include "More precisely; instead of" , "More willingly, by preference" , "Fairly" , "Slightly, more so than not (6" , "Yes, please!" .)
