Source: Browser Default
U+7814 "研" CJK Unified Ideograph-# is a Chinese character (hanzi) that is also used in Japanese and Korean, where it primarily conveys the meanings of "to grind," "to study," or "to research." Composed of the radical for stone (石) on the left and the phonetic component "开" on the right, its original sense relates to the physical action of grinding or sharpening a tool against a stone. Over time, this concrete action evolved into the abstract concepts of polishing knowledge and conducting investigation, making it a common character in scholarly and scientific contexts, such as in the word "研究" (research or study).
