What does moot mean?
A moot matter is one that is no longer relevant or worth arguing about, usually because it has already been settled by law, logic, or later circumstances. Saying that an objection or distinction is "moot" does not merely suggest that it is unimportant; it indicates that resolving it would not affect the outcome. The adjective is common in formal legal, academic, and governmental writing. The related verb, "to moot," means to raise a subject for discussion, as in "to moot a proposal," and is also mainly formal. A moot can, in less common usage, mean a question or issue under discussion. The word also survives in the legal expression "moot court," which refers to a court assembled to hear arguments, reflecting an older sense connected with meetings and debate. Together, these uses make moot distinctive: it often concerns questions that have become practically irrelevant, even when the underlying issue may once have mattered greatly.
Irrelevant or without practical effect, especially because the issue is settled or incapable of affecting the outcome.
"The question of damages was moot once the court dismissed the claim."
Formal and especially common in legal, academic, and governmental contexts.
To put a subject or proposal forward for discussion.
"Several members mooted the idea of holding an additional hearing."
Formal; commonly used in legal, political, and institutional discussion.
A subject or question under discussion, or, historically, an assembly or meeting.
"The committee treated the proposal as a moot for the following session."
The sense meaning a subject under discussion is uncommon; the assembly or meeting sense is largely archaic, though "moot court" remains established in legal usage.
Plural is uncommon; it is used mainly in the older sense of assemblies or meetings.
"The moot assembled to hear arguments from both sides."
In modern English, a moot issue is one that no longer needs discussion—but the legal phrase "moot court" preserves the older sense of an assembly gathered to debate matters.

Where does moot come from?
The word descends from Old English and is associated with the language of meetings, assemblies, and debate. Its modern legal senses developed from that older sense, while the familiar adjective meaning irrelevant or settled developed through the idea of a matter being argued without practical effect.
