Telegraph writer maybe regularly rues beer (8)
I believe the answer is:
reporter
'telegraph writer' is the definition.
'reporter' can be an answer for 'writer' (I've seen this before). I'm not certain of the 'telegraph' bit.
'regularly rues beer' is the wordplay.
'regularly' indicates alternate letters (regularly take one letter, leave next etc.).
'beer' becomes 'porter' (type of beer).
The alternate letters of 'rues' are 're'.
're'+'porter'='REPORTER'
'maybe' acts as a link.
Can you help me to learn more?
(Other definitions for reporter that I've seen before include "One gives us the news" , "Newspaper writer" , "One may get a story" , "Journo" , "Newspaperman" .)
