Nice lady's head held by boor (8)
I believe the answer is:
pleasant
'nice' is the definition.
(associated in meaning)
'lady's head held by boor' is the wordplay.
'lady's head' becomes 'l' (I can't justify this - if you can you should give a lot more credence to this answer).
'held by' indicates putting letters inside.
'boor' becomes 'peasant' (synonyms).
'l' put within 'peasant' is 'PLEASANT'.
Can you help me to learn more?
(Other definitions for pleasant that I've seen before include "Refreshing" , "Charming" , "A greeable, affable" , "Delightful" , "Enjoyable, nice" .)
