Ask enrolled nurse to negotiate (7)
I believe the answer is:
entreat
'ask' is the definition.
(I've seen this before)
'enrolled nurse to negotiate' is the wordplay.
'enrolled nurse' becomes 'en' (this could be a standard abbreviation which I don't know about).
'to negotiate' becomes 'treat' (I've seen this before).
'en'+'treat'='ENTREAT'
Can you help me to learn more?
(Other definitions for entreat that I've seen before include "Pray" , "petition" , "Sue" , "Beseech, implore" , "Beg earnestly or emotionally" .)
