Job, at old inn, has letters from apostle redirected (6)
I believe the answer is:
ostler
'job at old inn' is the definition.
I can't judge whether this definition defines the answer.
'letters from apostle redirected' is the wordplay.
'letters from' says the answer is hidden in the clue (a selection of letters from the clue).
'OSTLER' can be found hidden inside 'apostle redirected'.
'has' acts as a link.
Can you help me to learn more?
(Other definitions for ostler that I've seen before include "ER lost (anag) - former stableman" , "Formerly a stableman" , "Inn attendant (hist.)" , "Old stableman at an inn -- sterol (anag)" , "Inn's stable lad" .)
