The kanji 証 fundamentally means "evidence," "proof," "testimony," or "to prove." It signifies something that serves to support a claim, verify a fact, or provide confirmation. It implies the presence of something that can establish the truth or validity of a statement or event.

The kanji 証 is a phono-semantic compound (形声文字). The left side is a radical (部首) representing speech or language, specifically 言 (ことば/言, "word," "speech"). The right side is 正 (ただしい/正, "correct," "right," or "true"). The meaning combines these elements, with 言 indicating the need for words or statements (testimony) and 正 suggesting that this testimony is true or accurate. The combination of these parts creates the meaning of "evidence" or "proof" through the confirmation of spoken words.
