Write from Paris to The Thunderer? (6)
I believe the answer is:
author
'write' is the definition.
(authoring is a kind of writing)
'paris to the thunderer?' is the wordplay.
'paris' becomes 'au' (I am not sure about this - if you are sure you should believe this answer much more).
'to the thunderer?' becomes 'thor' (Norse thunder god).
'au'+'thor'='AUTHOR'
'from' acts as a link.
Can you help me to learn more?
(Other definitions for author that I've seen before include "Writer - initiator" , "Writer of a book, article or document" , "Ford, for example" , "Someone who originates, causes or initiates something" , "Ours wrote as Edward" .)
