The kanji 類類 is a phono-semantic compound (形声文字). The left side is a radical called 米, which represents "rice." The right side is a phonetic component 頁 (also often written as 貝), which originally meant "shell" or "bead," but over time it got used for its sound. The original meaning might have been related to the act of sorting or classifying rice. The 貝 part also suggests the gathering of similar things. Over time, the meaning shifted to represent various categories, kinds, or types.
