Consider internet wrong about answer (9)
I believe the answer is:
entertain
'consider' is the definition.
(I've seen this before)
'internet wrong about answer' is the wordplay.
'wrong' indicates anagramming the letters.
'about' indicates putting letters inside.
'answer' becomes 'a' (abbreviation eg in Q and A).
'internet' is an anagram of 'entertin'.
'entertin' placed around 'a' is 'ENTERTAIN'.
(Other definitions for entertain that I've seen before include "Train teen to amuse" , "harbour" , "Think about" , "Wine and dine" , "what the party host will do" .)
