See agenda in American Heritage Dictionary 4
noun pl. a·gen·das
Origin: , pl. of agendum, agendum; see agendum. Usage Note: It is true that Cicero would have used agendum to refer to a single item of business before the Roman Senate, with agenda as its plural. But in Modern English a phrase such as item on the agenda expresses the sense of agendum, and agenda is used as a singular noun to denote the set or list of such items, as in The agenda for the meeting has not yet been set. If a plural of agenda is required, the form should be agendas: The agendas of both meetings are exceptionally varied.
