Usage

Plural word for forum The plural form of forum can be either forums or fora. Forums is more widely used. The plurals of several other singular words that end in -um are formed in this way, including gum/gums, possum/possums, or geranium/geraniums. Irregular plurals that are formed like fora, such as curriculum/curricula and memorandum/memoranda, derive directly from their original pluralization in Latin. However, the standard English plural -s ending is often also acceptable for these terms, as in curriculums and memorandums.

Etymology

Origin of forum

First recorded in 1425–75; late Middle English, from Latin: “marketplace, public place,” akin to forīs, forās “outside,” foris door

Explanation

A forum is a public discussion. It can refer to a meeting, a meeting house or any conversation that is available publicly. There were forums — large public gathering places — in Ancient Rome; they can still be found across the globe. Traditionally, newspapers were thought of as forums for public discussions but more and more forums are virtual — discussion boards found online. Communities, however, still hold their own forums, or meetings, usually to discuss local issues. When you see the word forum, think public conversation.
