yonnin

Yonnin, usually written 四人 and read よにん (yonin), is a Japanese term that denotes a group of four people. It uses the counter nin attached to the numeral 四 to count people. The form is standard in everyday language and appears in both spoken and written Japanese.

In Japanese counting, distinct forms exist for one and two people (hitori for one, futari for two), after which the sino-Japanese numerals plus the counter nin are used for three and above (sannin for three, yonin for four, gonin for five, and so on). An example is 四人の学生がいます, read よにんのがくせいがいます, meaning there are four students in the classroom.

The word is common in ordinary contexts such as describing a quartet, organizing teams, or noting family or group size. It does not denote a specialized concept beyond counting four people, and it does not imply any particular order or role among the individuals.

Romanization and variants: the standard romanization is "yonin." The spelling "yonnin" may appear in nonstandard or non-Japanese sources, but it is not the typical or recommended form in modern usage.
