Odd saint given scope (7)
I believe the answer is:
strange
'odd' is the definition.
(I know that odd can be written as strange)
'saint given scope' is the wordplay.
'saint' becomes 'st' (abbreviation).
'given' is a charade indicator (letters next to each other).
'scope' becomes 'range' (synonyms).
'st'+'range'='STRANGE'
(Other definitions for strange that I've seen before include "Odd kind of garnets" , "Unknown or peculiar" , "Odd - rum" , "Odd, not familiar" , "Unusual, surprising" .)
