Did you know?

Referendum is a Latin word, but its modern meaning only dates from the 19th century, when a new constitution adopted by Switzerland stated that the voters could vote directly on certain issues. Thus, a referendum is a measure that's referred (that is, sent on) to the people. Since the U.S. Constitution doesn't provide for referenda (notice the common plural form) at the national level, referenda tend to be on local and state issues. In most locales, a few questions usually appear on the ballot at election time, often involving such issues as new zoning ordinances, new taxes for schools, and new limits on spending.

Examples of referendum in a Sentence
