We are looking at a triple threat set of homonyms. They sound alike but they have different meanings and uses. This is one of the wonderful parts of the English language, we have at our disposal so many ways to express different shades of meaning. With everything else in life, these words can also cause grief; if you use a correctly spelled word that sounds the same as the word you intended you will have a hidden spelling error. We call it hidden because most spell checkers won’t flag it as an error. The chosen word matches a word in the list of the spellchecker. Let us get on with it!
Eminent is a very common word, it means outstanding or famous in most senses of the usage. There is an extension in the realm of law and politics. When a governmental body uses its status to take control over private property, this is called Eminent Domain.
Imminent is a word almost as common as Eminent. Imminent means about to happen, likely to occur very soon. One of the most frequent phrases we see is “Imminent danger”.
Immanent is a word we seldom see. It is used by theologians and philosophers. The theological meaning refers to an attribute of God, that He is present everywhere throughout the universe at the same time. Philosophers use this term in their discussions to mean something is inherent.
There we are, three words that sound the same with different meanings. If used incorrectly will put a speed bump in an otherwise smooth drive for your readers.
