Falses

Falses is not a widely established technical term, but it can be encountered as the plural form of false when false is used as a noun to refer to false statements or propositions. In standard English, false is primarily an adjective; its use as a noun is rare and typically limited to informal or theoretical contexts. As such, falses may appear in discussions that treat multiple incorrect claims collectively, though more precise phrasing—such as false statements or false propositions—is usually preferred.

In logic and philosophy, truth values are usually described as true or false. When researchers or writers discuss several propositions that do not hold, they might informally refer to “falses” as a shorthand for those false propositions. However, this usage is not standard, and writers commonly use explicit terms like false statements or false propositions to avoid ambiguity.

In data science and machine learning, terminology tends to rely on categories such as true positives, false positives, true negatives, and false negatives. The plural falses is not a standard technical term in these fields, and it is generally avoided in favor of the more descriptive phrases that specify the nature of the incorrect results.

Etymology-wise, false comes from Old French fals, with Latin roots falsus meaning “deceived” or “false.” The plural suffix -es is a regular English formation, but applying it to an adjective used as a noun is unusual, contributing to its rarity in formal usage.
