Lexicographer, internet celebrity releasing article for magazine finally (7)
I believe the answer is:
webster
'lexicographer' is the definition.
(I know that Webster is a lexicographer)
'internet celebrity releasing article for magazine finally' is the wordplay.
I cannot really understand how this works, but
'internet' could be 'web' (I've seen this before) and 'web' is found within the answer.
The remaining letters 'ster' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for webster that I've seen before include "US lexicographer" , "Dramatist" , "American lexicographer" , "dictionary?" .)
