What does colloquia mean?
Colloquia is the plural of colloquium, a term drawn directly from Latin that denotes formal academic gatherings at which scholars present and discuss research on a shared subject. Typically organized as recurring series within universities, institutes, or professional departments, colloquia feature invited speakers, presented papers, and structured debate among participants. They differ from large conferences in being smaller, more sustained, and often tied to a single department or field. The word retains its Latin plural form in standard academic usage — the singular is colloquium — although the anglicized plural 'colloquiums' also appears. Because it belongs to a formal register, colloquia signals scholarly seriousness and intellectual community; it rarely surfaces outside academic writing. Related terms include colloquy, meaning a formal conversation, and colloquial, describing informal everyday speech. For students and researchers alike, attending colloquia remains a central ritual of academic life and professional exchange.

When academics want to sound extra scholarly about their meetings, they don't just hold conferences — they hold colloquia.

Etymology of colloquia
Colloquia comes from Latin, the plural of colloquium, which itself derives from col- ('together') plus loqui ('to speak') — literally 'a speaking together.' English adopted colloquium in the early modern period as a term for formal conversation or dialogue, and over time it came to denote scholarly discussion meetings. It shares the same Latin root with cognates such as eloquent, loquacious, and soliloquy.
