She's maybe in Madrid for the wrong reason (6)
I believe the answer is:
senora
'she's maybe in madrid for' is the definition.
I can't judge whether this defines the answer.
'wrong reason' is the wordplay.
'wrong' is an anagram indicator.
'reason' with letters rearranged gives 'SENORA'.
'the' is the link.
Can you help me to learn more?
(Other definitions for senora that I've seen before include "Spanish title" , "woman from Barcelona" , "Lady of Spain" , "Foreign lady; reason (anag.)" , "Lady overseas" .)
