Dance occurring in Ireland is complicated (5)
I believe the answer is:
disco
'dance' is the definition.
(disco can mean a dance event)
'in ireland is complicated' is the wordplay.
'in' indicates a hidden word.
'DISCO' is hidden in the letters of 'ireland is complicated'.
'occurring' acts as a link.
I am not very happy about this link. It may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for disco that I've seen before include "20 club" , "Thumping music" , "music supplier" , "One might get down to this" , "Musical party" .)
