Omni prefix. All, every, or universally present within a domain.
The prefix omni- comes from Latin omnis, meaning "all" or "every." It expands ordinary words into universal scope: omniscient (all-knowing), omnipresent (present everywhere), omnipotent (all-powerful).
Beyond grammar, omni-language can function as a philosophical pointer toward wholeness. It reminds us to think systemically, to look at interconnection rather than fragments, and to hold a wider field in mind before drawing conclusions.
"Omnis enim ex omnibus rebus paratur."
"Everything is prepared from all things."
- Lucretius, De Rerum Natura, Book I
In astronomy, all-sky surveys are sometimes described informally as "omni" projects because they attempt to map the full celestial sphere rather than a narrow slice of it.
Omni- marks a range that reaches wide,
expanding any term from every side;
it names the whole within a single span,
and broadens scope where lesser words began.
