Is there another omni- that goes with omnipresence omnipotence and omniscience?

You're right, there's a clear pattern with omnipresence (being everywhere), omnipotence (having unlimited power), and omniscience (knowing everything).

The missing word in this series is omnibenevolence, which means all-goodness or perfect goodness.

This concept is often associated with deities, suggesting that they are not only all-powerful and all-knowing, but also perfectly good and benevolent.
