What does roster mean?
A roster is an official or semi-official list of people associated with an organization, team, or military unit. It may simply identify all members, but it often also indicates availability, selection, or responsibility for particular duties. In sport, the roster is the group of players eligible to participate, while a business roster lists employees. A duty roster records who will perform scheduled tasks, often by day or shift. The word is especially familiar in American English for team and employee lists, although it is also used in British English, particularly in military and institutional settings. Roster can refer either to the written list or, more generally, to the people named on it. Its historical connection to a wooden tablet or board gives it a practical, administrative character: it is a record used to organize people and make clear who belongs, who is available, and who is responsible.

Where does roster come from?
The word entered English in the early 17th century from French roster, a word for a table or list, ultimately derived from Latin rostrum, meaning a beak or projecting wooden tablet. The original sense referred to a list of names displayed on such a tablet; in military use, the term came to mean the official list of soldiers. Related forms include rostrum, rostrate, rostral, and rostriform, all reflecting the Latin root’s associations with beaks, projecting structures, and tablets.
