Verbally cross and discourteous (4)
I believe the answer is:
rude
'discourteous' is the definition.
(thesaurus)
'verbally cross' is the wordplay.
'verbally' indicates a 'sounds like' (homophone) clue.
'cross' becomes 'rood' (term for a crucifix).
'rood' sounds like 'RUDE'.
'and' acts as a link.
(Other definitions for rude that I've seen before include "Discourteous or unrefined" , "Blue" , "Impudent" , "Unmannerly" , "so curt here?" .)
