Dash from Ireland (4)
I believe the answer is:
elan
'dash' is the definition.
(synonyms)
'from ireland' is the wordplay.
'from' indicates a hidden word.
'ELAN' is hidden in the letters of 'ireland'.
(Other definitions for elan that I've seen before include "Vigour, panache" , "Vigour, style, enthusiasm" , "French vivacity" , "Vivacity, panache" , "French flair" .)
