KK: /əˈdʒɛndəm/
A thing that needs to be done, often listed as part of a plan or agenda.
The first item on the agendum for the meeting was to discuss the budget.
Agendum is derived from the Latin word "agendum" (meaning something to be done), which is the neuter gerundive form of "agere" (meaning to do or to act). The word refers to a list of items to be acted upon or discussed.
Think of 'agere' meaning to 'do' — an agendum is a list of things that need to be done.
