Social blunder involving Irish animal (7)
I believe the answer is:
giraffe
'animal' is the definition.
(I've seen this before)
'social blunder involving irish' is the wordplay.
'social blunder' becomes 'gaffe' (I've seen this in another clue).
'involving' indicates putting letters inside.
'irish' becomes 'IR' (abbreviation).
'gaffe' going around 'ir' is 'GIRAFFE'.
(Other definitions for giraffe that I've seen before include "Long-necked ruminant" , "Long-necked mammal" , "Sixteen, mostly neck" , "Animal once known as a camelopard" , "that's beastly" .)
