Kawaii is the Japanese word for cute. In english it is usually reserved for anime girls. It has 4 syllables: ka wa i i.

If you pronounce it with english pronunciation, it sounds similar to the word "Kowai", which means scary/afraid. That is because in english, you don't fully pronounce nonstressed vowels, so kawai becomes kuh why. But in Japanese, you must pronounce all the vowels, so there is a difference.
