Definitions

1. Restoring pressure to a system or container that has lost or lost some of its original pressure; the process of increasing internal pressure to a desired level; making a system or environment regain its intended pressure condition
2. The act of reinstating proper pressure within a confined space or apparatus; reestablishing adequate pressure after a reduction or loss; adjusting pressure parameters to bring a system back to its optimal state
3. The procedure of raising pressure levels in equipment or an environment that had been decompressed or depressurized; returning the pressure to a preset norm; ensuring a container or system maintains appropriate pressure for operation

Etymology: "Repressurising" is the British spelling of "repressurizing", built from "re-" meaning "again" plus "pressurise", so it means restoring pressure to something that has lost it. The prefix "re-" reaches English through Old French from Latin, where it carried the same sense of repetition, and it attaches freely to verbs that describe a fresh start. The core of the word, "pressurise", goes back to Latin "pressura", a noun from "premere", "to press". English used "pressure" for physical force well before the technical sense of gas or fluid pressure took hold. The suffix "-ise" comes from Greek "-izein" by way of Late Latin "-izare" and Middle French "-iser", and it turns nouns and adjectives into verbs meaning "to make into" or "to subject to". Because "pressurise" describes making a sealed space hold a set pressure, most uses of "repressurise" involve aircraft cabins, spacecraft, or submarines that are restored to working pressure after a leak, a depressurisation, or a service opening.
