In Ireland, it means verve (4)
I believe the answer is:
elan
'verve' is the definition.
(I've seen this before)
'in ireland it' is the wordplay.
'in' indicates a hidden word.
'ELAN' is hidden in the letters of 'ireland it'.
'means' is the link.
(Other definitions for elan that I've seen before include "French verve" , "French flair" , "fizz" , "Grass with edible grains" , "French vivacity" .)
