Enraptured by a pronounced fragrance (4)
I believe the answer is:
sent
'enraptured' is the definition.
(sent can mean transported or absorbed)
'a pronounced fragrance' is the wordplay.
'a pronounced' indicates a 'sounds like' (homophone) clue.
'fragrance' becomes 'scent' (synonyms).
'scent' is a homophone of 'SENT'.
'by' is the link.
(Other definitions for sent that I've seen before include "Transported" , "Caused to go somewhere" , "Remitted" , "Shipped" , "charged with emotion?" .)
