From Latin agendum, substantive use of the neuter singular of agendus (“which ought to be done”), future passive participle (gerundive) of agō (“to do, act, make”).
Agendum is a word now so common in the plural that its plural form agenda is now generally taken to be a collective singular form, with the special meaning of a list of tasks which are to be done. A similar case is datum and its plural data which is now commonly taken to be a collective singular and synonymous with 'information'.
