Use imminent for something about to happen, and immanent for something existing within or throughout something else. A storm is imminent; a quality can be immanent in a person's character. The two share no meaning at all, only a similar sound.
The core difference
Imminent describes timing (soon to occur); immanent describes location or nature (inherent within something).
- immanent — naturally part of, or existing throughout, something: a sense of justice immanent in the community's laws.
- imminent — about to happen very soon: forecasters warned that a storm was imminent.
How to tell them apart
The mix-up is almost always a spelling slip, since the two words are pronounced very similarly and differ by only one letter. A useful anchor is that imminent shares its Latin root with eminent and mount — both carry a sense of something rising up or overhanging, which fits the idea of a threat looming close. Immanent, by contrast, comes from a root meaning to dwell or remain within, the same root found in remain and manor — a useful reminder that it is about staying inside something, not arriving soon.
Because imminent is by far the more commonly used word, writers reaching for it under time pressure sometimes type immanent by mistake. Reading the sentence back and asking whether the word describes a deadline or a quality usually settles which spelling is needed.
