Cxl is commonly used as an abbreviation for the word "cancel". However, there are a few synonyms that can be used in place of "cxl" or "cancel". Some alternatives include void, annul, scrap, revoke, repeal, nullify, negate, abolish, and terminate. These words can be used in various contexts, such as cancelling a reservation, an appointment, a contract, or a project. It is important to note that the choice of synonym may vary based on the situation. For example, "annul" may be more suitable for a legal document, while "scrap" may be more appropriate for a material or product that is no longer needed.
