Foreign or very strange (5)

I believe the answer is:

alien

I believe this is a double definition.

'foreign' is the first definition.
(synonyms)

'very strange' is the second definition.
(I've seen this in another clue)

(Other definitions for alien that I've seen before include "ET" , "Offensive" , "Creature from another planet" , "Foreigner, outsider" , "Clanger?" .)

I've seen this clue in the Irish Times (Simplex) and The Irish Times.
