Tale-teller is candid, love being rejected (8)
I believe the answer is:
franklin
'tale-teller' is the definition.
(teller of the Franklin's Tale in Canterbury Tales)
'candid love being rejected' is the wordplay.
'candid' becomes 'frank' ('frank' can be a synonym of 'candid').
'love' becomes 'nil' (I've seen this before).
'being rejected' is a reversal indicator.
'nil' backwards is 'lin'.
'frank'+'lin'='FRANKLIN'
'is' acts as a link.
(Other definitions for franklin that I've seen before include "Statesman" , "Benjamin or Roosevelt" , "old landowner" , "Tale-bearer" , "[PILGRIM in the CANTERBURY TALES]" .)
