Weather deity followed central assaults of the writer (6)
I believe the answer is:
author
'the writer' is the definition.
(synonyms)
'weather deity followed central assaults' is the wordplay.
'weather deity' becomes 'thor' (Thor is an example. I am not sure about the 'weather' bit.).
'followed' says to put letters next to each other.
'central' indicates the central letters.
The middle of 'assaults' is 'au'.
'thor' after 'au' is 'AUTHOR'.
'of' acts as a link.
Can you help me to learn more?
(Other definitions for author that I've seen before include "He wrote the book or play" , "Writer - initiator" , "Writer of a book, article or document" , "Writer of a book, say" , "Generator, writer" .)
