Crass and cross, reportedly? (4)
I believe the answer is:
rude
'crass' is the definition.
(I've seen this in another clue)
'cross reportedly?' is the wordplay.
'cross' becomes 'rood' (term for a crucifix).
'reportedly?' shows a homophone (sound like) (I've seen 'reportedly' mean this).
'rood' is a homophone of 'RUDE'.
'and' acts as a link.
(Other definitions for rude that I've seen before include "Impolite or vulgar" , "Uncivil" , "likely to offend" , "Uncouth" , "so curt here?" .)
