Paul, say, as recalled in Tarsus originally (5)
I believe the answer is:
saint
'paul say' is the definition.
(paul is a kind of saint)
'as recalled in tarsus originally' is the wordplay.
'recalled' says the letters should be written backwards.
'originally' suggests taking the first letters.
The first letter of 'tarsus' is 't'.
'as' reversed gives 'sa'.
'sa'+'in'+'t'='SAINT'
(Other definitions for saint that I've seen before include "Canonised person" , "Good woman" , "See 6" , "eg Paul, Peter, Valentine" , "paragon!" .)
