To participate in or conduct a colloquy; to have a formal conversation or discussion.
From colloquium (Latin col- 'together' + loqui 'to speak') + -ize (to make or engage in). A rare English formation paralleling how many Latin nouns receive the -ize verb treatment.
Colloquize is what happens when English speakers want to turn a noun into a verb—and it mostly failed because we prefer words like 'discuss' or 'converse.' But it reveals something cool: English is obsessed with turning things into actions, which is why we 'google' and 'text' and 'zoom' constantly.
