Japanese

As an adjective, it describes something or someone from Japan, such as Japanese food or Japanese culture. As a noun, it can mean the language spoken in Japan or a person from Japan.

Formed in English from “Japan” plus the adjective/noun-forming suffix “-ese,” which was borrowed from French and used for nationalities and languages. The base name “Japan” itself came through European versions of a Chinese name for the country. Over time, “Japanese” became the standard English term.
