What does roistered mean?
Roistered means formally entered on a roster or included among those assigned to a particular duty, team, shift, or period of service. The expression has an administrative tone and is especially associated with military personnel, emergency services, workplaces, and organized sports. Saying that someone was roistered for duty indicates more than simply being available: the person or unit has been entered on the responsible authority's official list. The word can also be used of organizations, particularly military units, when they are included in a schedule or assigned to a task. In everyday conversation, roistered may sound formal or slightly old-fashioned, but it remains precise and useful when describing official arrangements. Its sense also carries a mild implication of accountability, since a roster records who is expected to carry out a particular role.

Where does roistered come from?
The word derives from "roster," which entered English in the early 17th century from Dutch, where "rooster" referred to a list or roll of names. The English verb developed from the noun's older sense of an official list and later came to mean entering a person on a duty roster or assigning someone to service. The military use is especially influential in the modern meaning of "roistered."
