Intended holding name back (7)
I believe the answer is:
finance
'back' is the definition.
(thesaurus)
'intended holding name' is the wordplay.
'intended' becomes 'fiance' (I've seen this before).
'holding' means one lot of letters goes inside another.
'name' becomes 'n' (common abbreviation e.g. on forms).
'fiance' going around 'n' is 'FINANCE'.
(Other definitions for finance that I've seen before include "Provide funds for" , "sponsor" , "Public money" , "funding" , "Back" .)
