Canterbury pilgrim with tale is outspoken, having left home (8)
I believe the answer is:
franklin
'canterbury pilgrim with tale' is the definition.
(character in Chaucer's Canterbury Tales)
'outspoken having left home' is the wordplay.
'outspoken' becomes 'frank' (synonyms).
'having' says to put letters next to each other.
'left' becomes 'L' (common abbreviation).
'home' becomes 'in' ('he's home' can mean 'he's in').
'frank'+'l'+'in'='FRANKLIN'
'is' is the link.
(Other definitions for franklin that I've seen before include "old landowner" , "Statesman" , "Tale-bearer" , "[PILGRIM in the CANTERBURY TALES]" , "One with a tale to tell" .)
