Reportedly throw class (5)
I believe the answer is:
caste
'class' is the definition.
(caste is a kind of class)
'reportedly throw' is the wordplay.
'reportedly' shows a homophone (sound like).
'throw' becomes 'cast' (synonyms).
'cast' is a homophone of 'CASTE'.
(Other definitions for caste that I've seen before include "Hindu determinant of status" , "Hereditary Hindu social division" , "Level in society" , "A sect (anag)" , "Social group in India" .)
