Language of male getting cross (4)
I believe the answer is:
manx
'language' is the definition.
(Manx is an example)
'male getting cross' is the wordplay.
'male' becomes 'man' (man is a kind of male).
'getting' is a charade indicator (letters next to each other).
'cross' becomes 'x' (X is cross-shaped).
'man'+'x'='MANX'
'of' acts as a link.
(Other definitions for manx that I've seen before include "From an isle in the Irish Sea" , "Kind of cat" , "Island's" , "Breed of tailless cat" , "To do with the Isle of Man - say a cat" .)
