Reportedly perceives geographical features (4)
I believe the answer is:
seas
'geographical features' is the definition.
Although both the answer and definition are plural nouns, I can't see how one could define the other.
'reportedly perceives' is the wordplay.
'reportedly' shows a homophone (sound like).
'perceives' becomes 'sees' (seeing is a kind of perceiving).
'sees' is a homophone of 'SEAS'.
Can you help me to learn more?
(Other definitions for seas that I've seen before include "Aegean and Mediterranean, say" , "Oceans" , "Red and Black are" , "Red and Dead" , "Bodies of salt water" .)
