Deep engagement in something.
- In examining Capote, Clarke follows the course of the precocious writer's life with painstaking attention to gossipy detail. It's an exhaustive roller coaster of a read, a high-tilt immersion into the social swirl and scandal that accompanied most of Capote's adult life.1988 December 11, Elizabeth Pincus, “Truman Capote: The Gossip, The Dirt”, in Gay Community News, volume 16, number 22, page 7:

- She left the immersion on all the time, while I had been reared under pain of death to turn it off as soon as the bathwater was heated.2020, Kathleen MacMahon, Nothing But Blue Sky, Penguin, →ISBN:
Mathematics, Sciences A smooth map whose differential is everywhere injective, related to the mathematical concept of an embedding.

Astronomy, Natural sciences The disappearance of a celestial body, by passing either behind another, as in the occultation of a star, or into its shadow, as in the eclipse of a satellite.

Education A form of foreign-language teaching where the language is used intensively to teach other subjects to a student.
- Although numerous studies have reported the effectiveness of immersion programmes in developing relatively high levels of second language proficiency without any tradeoff of first language development or subject matter mastery, little is known of immersion education in Japan.2001, Mary Goebel Noguchi, Sandra Fotos, Studies in Japanese Bilingualism, Multilingual Matters, →ISBN, page 272:
One's suspension of disbelief while reading, playing a video game, etc. The experience of losing oneself in a fictional world.
