Reserved embrace for moneylender (7)
I believe the answer is:
shylock
'moneylender' is the definition.
(thesaurus)
'reserved embrace' is the wordplay.
'reserved' becomes 'shy' (I've seen this before).
'embrace' becomes 'lock' (locking is a kind of embracing).
'shy'+'lock'='SHYLOCK'
'for' is the link.
(Other definitions for shylock that I've seen before include "Famous loner reportedly" , "27's usurer" , "Heartless creditor" , "Moneylender in "The Merchant of Venice"" , "Shakespearean character" .)
