Suffrage is often conceived in terms of elections for representatives. However, suffrage applies equally to referenda and initiatives. Suffrage describes not only the legal right to vote, but also the practical question of whether a question will be put to a vote. The utility of suffrage is reduced when important questions are decided unilaterally by elected or non-elected representatives.
In most democracies, eligible voters can vote in elections of representatives. Voting on issues by referendum may also be available. For example, in Switzerland this is permitted at all levels of government. In the United States, some states such as California and Washington have exercised their shared sovereignty to offer citizens the opportunity to write, propose, and vote on referendums and initiatives; other states and the federal government have not. Referendums in the United Kingdom are rare.
Suffrage is granted to qualifying citizens once they have reached the voting age. What constitutes a qualifying citizen depends on the government's decision. Resident non-citizens can vote in some countries, which may be restricted to citizens of closely linked countries (e.g., Commonwealth citizens and European Union citizens).
The word suffrage comes from Latin suffragium, meaning "vote", "political support", and the right to vote. The etymology of the Latin word is uncertain, with some sources citing Latin suffragari "lend support, vote for someone", from sub "under" + fragor "crash, din, shouts (as of approval)", related to frangere "to break" (related to fraction and fractious "quarrelsome"). Other sources say that attempts to connect suffragium with fragor cannot be taken seriously. Some etymologists think the word may be related to suffrago and may have originally meant an ankle bone or knuckle bone.
Universal suffrage consists of the right to vote without restriction due to sex, race, social status, education level, or wealth. It typically does not extend the right to vote to all residents of a region; distinctions are frequently made in regard to citizenship, age, and occasionally mental capacity or criminal convictions.
