European run taking in Northern Ireland (6)
I believe the answer is:
danish
'european' is the definition.
(I've seen this before)
'run taking in northern ireland' is the wordplay.
'run' becomes 'dash' (dash is a kind of run).
'taking in' means one lot of letters goes inside another.
'northern ireland' becomes 'ni'.
'dash' placed around 'ni' is 'DANISH'.
(Other definitions for danish that I've seen before include "Language of Denmark" , "Hamlet was and bacon may be" , "Like Hans Andersen" , "Popular piece of pastry" , "accompaniment to coffee" .)
