I can still change hint (9)
I believe the answer is:
scintilla
'hint' is the definition.
(thesaurus)
'i can still change' is the wordplay.
'change' indicates anagramming the letters.
'i'+'can'+'still'='icanstill'
'icanstill' with letters rearranged gives 'SCINTILLA'.
(Other definitions for scintilla that I've seen before include "Tiny, scarcely detectable amount" , "Slight amount" , "The smallest amount" , "suspicion" , "A tiny bit" .)
