The word 你好 is formed by combining two independent characters: 你 (nǐ), meaning "you", and 好 (hǎo), meaning "good" or "well". It is a conceptual fusion where the notion of "you" is directly linked with the state of "goodness", creating a composite idea that functions as a direct address wishing well-being upon the person being spoken to. This formation is not a grammatical sentence but a solidified, conventional unit where the two components merge into a single social greeting meaning "hello".
