Can I still supply a hint? (9)
I believe the answer is:
scintilla
'a hint?' is the definition.
(both can mean a small amount)
'can i still supply' is the wordplay.
'supply' is an anagram indicator (in a supple way).
'can'+'i'+'still'='canistill'
'canistill' is an anagram of 'SCINTILLA'.
(Other definitions for scintilla that I've seen before include "The smallest amount" , "Tiny trace or amount" , "Slight amount" , "littlest bit" , "suspicion" .)
