Carmen, for example, seen in Europe rarely (5)
I believe the answer is:
opera
'carmen for example' is the definition.
(Carmen is an example)
'in europe rarely' is the wordplay.
'in' says the answer is hidden in the clue.
'OPERA' can be found hidden inside 'europe rarely'.
'seen' is the link.
(Other definitions for opera that I've seen before include "Grand or comic work?" , "E.g. Falstaff, Fidelio" , "Met show?" , "eg Otello" , "Throw a rope for this show" .)
