Saint Raymond the Wanderer (5)
I believe the answer is:
stray
'wanderer' is the definition.
(I've seen this in another clue)
'saint raymond' is the wordplay.
'saint' becomes 'st' (abbreviation).
'raymond' becomes 'ray' (Ray is short for Raymond).
'st'+'ray'='STRAY'
'the' acts as a link.
(Other definitions for stray that I've seen before include "Go off course" , "Drift - isolated" , "out of place" , "Vagrant" , "digress" .)
