A bit of an idiot, actually! (4)

I believe the answer is:

iota

'a bit' is the definition.
(I have seen 'Tiny bit' mean 'iota' so perhaps 'bit' could also mean 'iota')

'of an idiot actually' is the wordplay.
'of' indicates the answer is hidden within the clue.
'IOTA' is hidden within 'idiot actually'.

(Other definitions for iota that I've seen before include "Trace" , "Jot, particle" , "Tiny or scarcely detectable amount" , "Tiny piece" , "Just a jot, from Greek alphabet" .)

I've seen this clue in The Telegraph.
