In a way that strays from the main topic or subject, often covering a range of different ideas or points.
The lecture was delivered excursively, touching on various subjects rather than focusing on one.
Excursively → It is formed from "ex-" (meaning out of or from) and "curs-" (from Latin "currere", meaning to run) and the suffix "-ively" (meaning in a manner). The word "excursively" means in a manner that runs out or extends outward.
Think of 'running out' ('ex-') from a path ('curs-') to remember that 'excursively' describes something that extends outward.
