What term refers to a law enacted by a city or town?

The correct term for a law enacted by a city or town is "ordinance." An ordinance is a local law or regulation that is specifically designed to address issues within a municipality. These laws are created by local governing bodies, such as city councils or town boards, and typically govern matters such as zoning, building codes, or public safety.

Understanding the distinction between ordinance and other types of laws is important. Statutes, for instance, are laws enacted by state or federal legislatures, while regulations are rules created by governmental agencies to enforce laws. Bylaws usually refer to rules established by organizations or corporations to govern their internal affairs. Therefore, "ordinance" specifically captures the essence of a local law enacted by a city or town, making it the appropriate choice.
