Women pine regularly for young men's embrace (6)
I believe the answer is:
ladies
'women' is the definition.
(lady is a kind of woman)
'pine regularly for young men's embrace' is the wordplay.
I cannot quite see how this works, but
'pine' could be 'die' (dying is a kind of pining) and 'die' is located in the answer.
The remaining letters 'las' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
(Other definitions for ladies that I've seen before include "Women, of refinement perhaps" , "Well-mannered women" , "...... and gentlemen" , "Lords' wives" , "9th" .)
