Raw volunteer (6)
I believe the answer is:
tender
I believe this is a double definition.
'raw' is the first definition.
(thesaurus)
'volunteer' is the second definition.
(tender can mean to offer or volunteer)
(Other definitions for tender that I've seen before include "Caretaker" , "Ship that provides supplies to other ships" , "Offer for acceptance" , "Make offer in gentle way" , "Gentle and sore" .)
