Compiler right to feature in the Guardian or Telegraph (4)
I believe the answer is:
wire
'telegraph' is the definition.
(I know that telegraph can be written as wire)
'compiler right to feature in the guardian' is the wordplay.
'compiler' becomes 'I' (the person who is writing these clues).
'right' becomes 'r' (common abbreviation).
'to feature in' means one lot of letters goes inside another.
'the guardian' becomes 'we' (the crossword setter and their Guardian colleagues).
'i'+'r'='ir'
'ir' going inside 'we' is 'WIRE'.
'or' acts as a link.
(Other definitions for wire that I've seen before include "See 2" , "Thin metal thread" , "Cable" , "See 20" , "Hand signal; breaker" .)
