Allowance from crown included in dispatch (7)
I believe the answer is:
stipend
'allowance' is the definition.
(thesaurus)
'crown included in dispatch' is the wordplay.
'crown' becomes 'tip' ('tip' can be a synonym of 'crown').
'included in' means one lot of letters goes inside another.
'dispatch' becomes 'send' (I've seen this before).
'tip' placed within 'send' is 'STIPEND'.
'from' acts as a link.
(Other definitions for stipend that I've seen before include "Official income of Protestant clergyman" , "Remuneration" , "Regular money" , "Clerical salary" , "Clergyman's salary" .)
