a singular item on a list of things to be done; an individual agenda item (archaic singular of agenda).
From Latin 'agenda' (things to be done), 'agend' represents an attempted back-formation creating a singular form. In modern English, we typically use 'agenda item' or 'issue' instead.
This word shows how English speakers sometimes try to 'fix' Latin plurals—we did it with 'datum' from 'data,' but with 'agenda' it never caught on because 'agenda' itself already acts as a mass noun in modern usage.
