A ballot is a device (originally a small ball—see blackball) used to record decisions made by voters. Each voter uses one ballot, and ballots are not shared. In the simplest elections, a ballot may be a simple scrap of paper on which each voter writes in the name of a candidate, but governmental elections use pre-printed to protect the secrecy of the votes. The voter casts his/her ballot in a box at a polling station. In British English, this is usually called a "ballot paper". The word "ballot" is used for an election process within an organisation (such as a trade union "holding a ballot" of its members).
