Famous English diarist (5)
I believe the answer is:
pepys
'famous english diarist' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for pepys that I've seen before include "Diary-writer" , "Samuel -, noted diarist" , "Samuel ---, C seventeen Admiralty secretary" , "London diarist" , "English civil servant and diarist, d. 1703" .)
