Odd, strange (8)
I believe the answer is:
peculiar
This clue is a double definition.
'odd' is the first definition.
(I know that odd can be written as peculiar)
'strange' is the second definition.
(similar in meaning)
(Other definitions for peculiar that I've seen before include "'Strange, odd (8)'" , "Odd, rum, funny" , "Unusual" , "Out of the ordinary" , "Strange, I clear up" .)
