omnis

Omnis is a Latin adjective meaning "all" or "every," used to express totality. In Latin it modifies nouns and agrees with the noun’s gender and number; the neuter singular form is typically stated as "omne," with plural forms such as "omnia" for neuter. The term appears in classical Latin texts as a standard descriptive word for universality.

The principal legacy of omnis in English is the prefix omni-, meaning "all" or "every," which appears in many words that convey universality. Common examples include omniscient (knowing everything), omnipotent (all-powerful), omnipresent (present everywhere), and omnivorous (feeding on all kinds of food). Other derivatives include words like omni-benevolent, used in theological and philosophical contexts to describe a being that is all-good.

In modern usage, omnis as a standalone term is primarily encountered in discussions of Latin grammar, classical texts, or linguistic history. In English, the influence of the word is largely felt through the prefix omni-, which combines with various stems to form terms across theology, philosophy, science, and everyday language. The concept remains a useful reference point for understanding how languages shape compounds that convey comprehensive scope.
