Awfully I danced -- and it showed (9)
I believe the answer is:
indicated
'showed' is the definition.
('indicate' can be a synonym of 'show')
'awfully i danced and it' is the wordplay.
'awfully' indicates anagramming the letters.
'and' means one lot of letters go next to another.
'i'+'danced'='idanced'
'idanced' after 'it' is 'itidanced'.
'itidanced' with letters rearranged gives 'INDICATED'.
(Other definitions for indicated that I've seen before include "Shown" , "Signalled" , "advised" , "Pointed, showed" .)
