A more thorough explanation:

Definition: A record of a court's or public office's proceedings. It can also refer to an official list of the persons and property subject to taxation or the roster of those entitled to vote in parliamentary law.

• A court keeps a roll of all the cases it has heard and their outcomes.
• The tax roll lists all the properties and individuals subject to taxation in a particular area.
• During a parliamentary vote, the roll is called to determine who is eligible to vote.

The examples illustrate how a roll can be used to keep track of important information in different contexts. In a court, the roll helps to maintain a record of legal proceedings. In taxation, the roll is used to identify who needs to pay taxes. In parliamentary law, the roll is used to determine who can participate in a vote.
