An aroma that's pronounced, you agree (6)
I believe the answer is:
assent
'agree' is the definition.
(assenting is a kind of agreeing)
'an aroma that's pronounced' is the wordplay.
'an' becomes 'a'.
'aroma' becomes 'scent' (synonyms).
'that's pronounced' indicates a 'sounds like' (homophone) clue.
'a'+'scent'='ascent'
'ascent' is a homophone of 'ASSENT'.
'you' is the link.
(Other definitions for assent that I've seen before include "Acquiesce, comply" , "Acquiescence" , "Accede, agree" , "Give consent" , "Official sanction" .)
