Curious -- being fine, I sat dance out (10)
I believe the answer is:
fascinated
'curious' is the definition.
(thesaurus)
'fine i sat dance out' is the wordplay.
'fine' becomes 'f' (abbreviation).
'out' indicates anagramming the letters (out can mean wrong or inaccurate).
'i'+'sat'+'dance'='isatdance'
'isatdance' is an anagram of 'ascinated'.
'f'+'ascinated'='FASCINATED'
'being' acts as a link.
(Other definitions for fascinated that I've seen before include "spellbound" , "captured" , "Irresistibly interested" , "Captivated" , "Irresistably attracted" .)
