Embarrass new copper with award hero essentially receives (8)
I believe the answer is:
encumber
'embarrass' is the definition.
(thesaurus)
'new copper with award hero essentially receives' is the wordplay.
'new' becomes 'n' (common abbreviation eg NT for New Testament).
'copper' becomes 'Cu' (chemical symbol).
'with' is a charade indicator (letters next to each other).
'award hero essentially' becomes 'ember' (I can't explain this - if you can you should give a lot more credence to this answer).
'receives' is an insertion indicator (inserted letters are received).
'n'+'cu'='ncu'
'ncu' inserted into 'ember' is 'ENCUMBER'.
Can you help me to learn more?
(Other definitions for encumber that I've seen before include "Burden with a load, of debt perhaps" , "Burden with, oppress (8)" , "Impede, burden" , "Constrain" , "Be a burden to, place load on" .)
