Preliminary measure is a term used to describe an action taken before a more permanent solution is implemented. It is often used in the context of legal proceedings, where a court may issue a PRELIMINARY measure to protect a party's rights until a final decision is made. The term can also be used in other contexts, such as business or politics, to refer to a temporary solution that is put in place while a more permanent solution is being developed. The term 'PREP' is an abbreviation for the word 'PRELIMINARY, ' and is often used in the same context.
