The kanji 据 primarily conveys the idea of "to put", "to place", "to set", or "to base something on". It implies a sense of positioning, establishing, or fixing something in a specific location or context. This can refer to both physical placement and the act of establishing something abstract. It often suggests a sense of stability or fixing something in a certain state.

The kanji 据 is a phono-semantic compound (形声文字, keisei moji). The left side is a radical (部首, bushu) "扌" (てへん, tehen), meaning "hand". The right side is "居" which serves as the phonetic component, indicating the sound (kyo) and also related to the meaning, as it originally meant "to dwell" or "to be". Thus the whole character represents the act of using the hand (扌) to "place" or "set" something (居).
