Extraordinary, curious (7)
I believe the answer is:
bizarre
I believe this clue is a double definition.
'extraordinary' is the first definition.
(thesaurus)
'curious' is the second definition.
(thesaurus)
(Other definitions for bizarre that I've seen before include "Off-the-wall" , "Weird and wonderful" , "Freakish" , "Very strange" , "Funny" .)
