* To keep something safe from damage or decay: "We need to preserve our natural resources."
* To keep something in its original state: "The museum preserves ancient artifacts."
* To prepare food by pickling, canning, etc.: "She preserves her own jams and jellies."
* A specialized term: It could be a technical term used in a specific field, like:
* Industry: A company or product name.
* Science: A scientific process or concept.
