Fool that was improperly taught, initially (4)
I believe the answer is:
twit
'fool' is the definition.
(thesaurus)
'that was improperly taught initially' is the wordplay.
'that was' becomes 'tw' (this could be a standard abbreviation of which I'm unaware).
'initially' says to take the initial letters.
The first letters of 'improperly taught' is 'it'.
'tw'+'it'='TWIT'
Can you help me to learn more?
(Other definitions for twit that I've seen before include "Silly person; tease" , "Twerp" , "Bait - fool" , "Nincompoop" , "Ninny" .)
