Copy page getting annoyed (6)
I believe the answer is:
pirate
'copy' is the definition.
(thesaurus)
'page getting annoyed' is the wordplay.
'page' becomes 'p'.
'getting' is a charade indicator (letters next to each other).
'annoyed' becomes 'irate' (I've seen this before).
'p'+'irate'='PIRATE'
(Other definitions for pirate that I've seen before include "Rat pie (anag)" , "sailor" , "Buccaneer, sea robber" , "Copy published material illegally" , "Copyright infringer" .)
