Dash from Ireland (4)
I believe the answer is:
elan
'dash' is the definition.
(I know that dash can be written as elan)
'from ireland' is the wordplay.
'from' says the answer is hidden in the clue.
'ELAN' can be found hidden inside 'ireland'.
(Other definitions for elan that I've seen before include "Vigour, panache" , "Vigour, style, enthusiasm" , "French vivacity" , "Vivacity, panache" , "French flair" .)
