Jokainen

Jokainen is a Finnish word meaning "every" or "each," and it can also function as the pronoun "everyone." It is used to indicate that all members of a defined group are included, and it can modify a noun or stand alone as a predicator. For example, Jokainen opiskelija sai kirjan (Every student received a book) or Jokainen voi osallistua (Everyone can participate). In formal language and logic, jokainen is used to express universal quantification, roughly aligning with the idea of "for all" in mathematical contexts.

Grammatical notes: Jokainen is declined like an adjective or pronoun in Finnish and has several inflected forms. The base form is jokainen; common forms include jokaisen (genitive), jokaiselle (allative), and jokaisessa (inessive), among others. In everyday speech, it typically sits before a noun, as in jokainen lapsi or jokainen meistä, and its meaning shifts slightly with the case of the following noun or pronoun.

Etymology and nuance: Jokainen is derived from the word joka, meaning "which" or "every," with the adjectival suffix -inen. The term is closely related to, but not always interchangeable with, kaiki (all). Jokainen often emphasizes individuality within a group, while kaikki more directly conveys totality. In common usage, jokainen tends to highlight the notion of each member’s participation or responsibility within a set.
