The Canterbury Tales author (7)
I believe the answer is:
chaucer
'the canterbury tales author' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for chaucer that I've seen before include "14th-century English poet" , "Geoffrey . . . . . . ., author of 'The Canterbury Tales'" , "Geoffrey ---, C14 poet" , "Poet known as the father of English literature, d. 1400" , "Early English writer" .)
