Tease for being a bit of a nitwit (4)
I believe the answer is:
twit
'tease' is the definition.
(I know that tease can be written as twit)
'being a bit of a nitwit' is the wordplay.
'TWIT' is hidden in amongst the letters.
However, I am unsure how this is indicated.
'for' acts as a link.
Can you help me to learn more?
(Other definitions for twit that I've seen before include "Silly person; tease" , "Silly person (colloq.)" , "Slangily a foolish person" , "Tease - fool" , "Silly fool" .)
