Unusual to have year in exotic capital (8)
I believe the answer is:
atypical
'unusual' is the definition.
(synonyms)
'year in exotic capital' is the wordplay.
'year' becomes 'y'.
'in' indicates putting letters inside.
'exotic' is an anagram indicator.
'capital' anagrammed gives 'atpical'.
'y' going into 'atpical' is 'ATYPICAL'.
'to have' is the link.
(Other definitions for atypical that I've seen before include "Not as expected" , "Nonconforming" , "out of character" , "Not characteristic" , "Abnormal, aberrent." .)
