omne

Omne is a Latin adjective in its neuter singular form, meaning “all” or “every.” It is the neuter form of omnis, an adjective used to express totality, and it is the linguistic source of the English prefix omni-.

Usage in Latin centers on agreement with the noun it modifies. In the neuter singular, omne corresponds to neuter nouns and appears in nominative and accusative cases. In the neuter plural, the form omnia serves as the nominative and accusative. Beyond agreement, omne can function as a substantive to mean “the whole” or “everything” when the noun is not explicitly stated, a common device in Latin where the concept is understood from context.

Classical and later Latin texts employ omne to denote entirety across a range of subjects, from physical wholes to abstract totalities. The form’s primary purpose remains indicating that every part or all of something is included, rather than describing a single item.

Influence outside Latin remains most visible through the prefix omni-, which derives from omnis and conveys the sense of universality in many English words, such as omnipotent, omnipresent, and omniscient. In modern usage, omne itself is rarely encountered outside scholarly or historical Latin discussions, but the term is still recognized as part of Latin grammatical morphology and etymology.
