The kanji 是 primarily means "is," "this is," "correct," "right," or "affirmative." It signifies a statement of fact or truth, and it can indicate something being true or accurate. It often functions as a copula, linking a subject to its attribute or description.

・On-yomi (音読み): ゼ (ze) ・Kun-yomi (訓読み): None, but it often functions as a particle.

⚫︎ これは是です。 Translation: This is it. / This is correct. ⚫︎ 是非 Translation: right and wrong; pros and cons ⚫︎ 是認する Translation: to admit; to acknowledge

Unfortunately, I cannot provide a direct correspondence between this kanji and Vietnamese. However, it's worth noting that Vietnamese utilizes many Sino-Vietnamese (漢越語) words derived from Chinese, and you may find related terms based on the context of the word itself.

The kanji 是 is a phono-semantic compound (形声文字). The top part 止 (shi), which means "foot" or "to stop," and originally indicated a foot on the ground. The bottom part 正 (sei/shō), meaning "correct" or "upright," suggests the concept of "correctness" or "what is right." Together, the kanji depicts something that is fixed or certain, something that "stops" at being true or correct. Over time, it evolved to represent the concept of "is" or "this is."
