What is a prefix that fits all or everywhere?

There isn't one single prefix that perfectly conveys "all or everywhere." However, depending on the context, you could use several prefixes to get close:

General:

* Omni-: Means "all" or "every." Examples: omnipresent (present everywhere), omnipotent (all-powerful).

* Pan-: Means "all" or "entire." Examples: pandemic (affecting all), panorama (a view of everything).

* Universal-: Means "pertaining to the universe or everything." Examples: universal law, universal truth.

Specific to place:

* Ubi-: Means "everywhere" or "anywhere." Example: ubiquitous (being everywhere).

Other options:

* Total-: Means "complete" or "entire." Examples: total eclipse, total destruction.

* Whole-: Means "entire" or "complete." Examples: wholehearted, whole number.

The best prefix will depend on the specific meaning you want to convey. For example, "omnipresent" implies a constant presence everywhere, while "ubiquitous" suggests a widespread but not necessarily constant presence.
