Prompt Title: Sino-xenic vocabulary in Sinosphere.

Sino-xenic vocabulary refers to words in East Asian languages, including Japanese, Korean, and Vietnamese, that are based on Chinese characters. This phenomenon arose from the widespread use of Chinese characters as the writing system in East Asia for over a thousand years.

As a result of this shared writing system, many East Asian languages have incorporated Chinese words into their vocabulary. However, the pronunciation and meaning of these words often evolved in different ways across different languages. For example, the Chinese character "人" (rén) means "person" in Mandarin Chinese, but in Japanese it is pronounced "jin" and means "person" as well as "people" or "nation".

This borrowing of Chinese words into other East Asian languages is not limited to just nouns, but also includes adjectives, verbs, and adverbs. In some cases, the Chinese character-based words have been further adapted to suit the specific grammar and syntax of the borrowing language.

The use of Sino-xenic vocabulary has been particularly strong in the so-called "Sinosphere" or "Sinophone" world, which encompasses East and Southeast Asia. This shared linguistic heritage has facilitated cultural exchange and has contributed to the formation of a pan-East Asian identity.
