One making progress with fathers? (7)
I believe the answer is:
pilgrim
'one making progress with fathers?' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
This is all the clue.
Can you help me to learn more?
(Other definitions for pilgrim that I've seen before include "made progress, as booked" , "One journeying to shrine etc" , "One progressive type" , "Palmer" , "Visitor to shrine" .)
