Korean food is known for its spice so knowing this adjective is SO important.
맵다 - To be spicy
매워요 - It is spicy
As a foreigner, when you order things the waiters will often ask you:
이것 너무 매워요. 괜찮아요?
(ee-geo neo-mu mae-weo-yo. kwaen-chan-a-yo?)
This is really spicy, are you sure that's okay?
It's sort of customary for older Korean people to think that foreigners can't handle Korean spicy food, so don't get angry - they're just looking out for you!
If you see this in front of something you know it's spicy
매운 ______ - Spicy _____
얼큰 ______ - Traditional spicy _____
Some of my favorite spicy Korean foods:
떡볶이 - spicy rice cakes
순두부찌개 - soft tofu stew
비빔밥 - bibimbap!
김치볶으밥 - kimchi fried rice
