A little prat, with an idiot (4)

I believe the answer is:

twit

'idiot' is the definition.
(I've seen this in other clues)

'a little prat with an' is the wordplay.
'a little' indicates the answer is hidden within the clue.
'TWIT' is hidden within 'prat with an'.

(Other definitions for twit that I've seen before include "Tease - fool" , "Bait - fool" , "Silly ass" , "Silly person (colloq.)" , "Idiot; tease" .)

I've seen this clue in The Everyman puzzle in The Observer.
