Eminent, immanent, and imminent are all adjectives. (The noun forms are eminence, immanence, and imminence).

With a meaning similar to “inherent,” immanence is often part of philosophical discussions about whether divinity permeates (dwells within) or transcends (is separate from) a Supreme Being’s creations. Eminence is used in some religions (e.g., Roman Catholic, Greek Orthodox) when addressing certain members of the clergy.

Something (or someone) eminent stands out (one meaning is to jut out or project); thus, an eminent person stands out from the crowd in some respect. A preeminent (sometimes hyphenated, pre-eminent) person is outstanding and superior to all others.

If something is imminent, it is about to happen (immediately!).

[Immanant is a mathematical term.]
