The word "moot" refers to a topic or issue that is open to discussion or debate, often because it is not currently relevant or significant. In legal contexts, it can mean a case that is no longer relevant due to changes in circumstances. Essentially, something that is moot does not warrant further consideration because it has been rendered irrelevant or hypothetical.
The word "moot" originates from the Old English word "mōt," which meant "meeting" or "assembly." It later evolved in Middle English to refer to a discussion or debate. Over time, the meaning shifted to refer to topics that are subject to debate but lack practical relevance.
