Learn Japanese adjectives

Japanese adjectives are categorized into three types. The first one is called “i adjective” and the second one is “na adjective”. The third one is irregular adjective. I adjectives end in “i”. For instance, Omoshiroi (funny), Tanoshii (Enjoyable), Chiisai (Small) are all i adjectives. Examples of Na adjectives include Shizuka (quiet), Yuumei (famous), Kirei (beautiful), and it can be confusing since Kirei is part of Na adjectives. Na adjectives usually do not end in ~i but some of them end in ~rei just like Kirei. There is only one irregular adjective in Japanese language, and it is “ii” or “yoi”(good).
