You might be referring to "imminent" "eminent" "immanent". "Imminent" is a commonly used adjective to describe something which is going to happen very soon but we don't know the exact time e.g. an increase in the oil price is imminent "Eminent" - is a formal but well-known and used adjective to describe someone who is very senior, well-respected and experienced in their field of work or study e.g. He is an eminent physician "Immanent" is a very unusual word used in philosophy. It's opposite is transcendent. It is used to explain that the origin of a "being" and / or its existence comes from within i.e. it was not created or held in being by an external, transcendent being. I may not have expressed this perfectly as I am only an armchair philosopher, not an eminent specialist!

That's right. Neither of those words exists. Michael has given you an excellent definition of three similar words which do exist, though.

I don't think those two words exist. Do you mean "imminent" or "immanent" and "eminent" maybe?
