Tall creature makes a blunder around Irish (7)
I believe the answer is:
giraffe
'tall creature' is the definition.
(I've seen this before)
'a blunder around irish' is the wordplay.
'a blunder' becomes 'gaffe' (gaffe is a kind of blunder).
'around' indicates putting letters inside.
'irish' becomes 'IR' (abbreviation for Irish).
'gaffe' enclosing 'ir' is 'GIRAFFE'.
'makes' acts as a link.
(Other definitions for giraffe that I've seen before include "wild beast" , "Animal once known as a camelopard" , "Tallest land animal" , "Large African mammal" , "A long-legged creature" .)
