His poetry, with a bit of luck, is possibly within reach (7)
I believe the answer is:
chaucer
'his poetry with a bit of luck is possibly within reach' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
This is the entire clue.
Can you help me to learn more?
(Other definitions for chaucer that I've seen before include "See 22 Across" , "Medieval poet" , "English author of The Canterbury Tales" , "Early English poet" , "Poet known as the father of English literature, d. 1400" .)
