Tastefully eccentric? (5)
I believe the answer is:
nutty
'eccentric?' is the definition.
(thesaurus)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for nutty that I've seen before include "Crunchy" , "Insane" , "Mentally unhinged (slang)" , "passionate" , "19 [LUNATIC]" .)
