Foreign saint sounded English (7)
I believe the answer is:
strange
'foreign' is the definition.
(I know that foreign can be written as strange)
'saint sounded english' is the wordplay.
'saint' becomes 'st' (abbreviation).
'sounded' becomes 'rang' (ringing is a kind of sounding).
'english' becomes 'E' (abbreviation as in OED).
'st'+'rang'+'e'='STRANGE'
(Other definitions for strange that I've seen before include "Funny" , "Odd or unfamiliar" , "Offbeat" , "Super for a couple here" , "Peculiar; Morse's boss" .)
