Reportedly recognises organ (4)
I believe the answer is:
nose
'organ' is the definition.
(nose is a kind of organ)
'reportedly recognises' is the wordplay.
'reportedly' indicates a 'sounds like' (homophone) clue.
'recognises' becomes 'knows' (know can mean to recognise someone).
'knows' is a homophone of 'NOSE'.
(Other definitions for nose that I've seen before include "Pry" , "Olafactory organ" , "scent" , "See 7" , "Faculty for detecting" .)
