Do you see the difference: one is 'feindlich' (means hostile, unfriendly) and the other one is 'freundlich' (means friendly)

der Ausländer – foreigner (Plural form – die Ausländer)

Examples:

Er ist ausländerfeindlich - He is hostile to foreigners.

Sabine ist ausländerfreundlich - Sabine is friendly to foreigners.

Warum war er so ausländerfeindlich? - Why was he so hostile to foreigners?
