Radiuse

Radiuse is not a widely recognized term in standard mathematics or science, and its meaning depends on context. In many cases, radiuse appears as a misspelling or nonstandard variant of radius, or as a coined term in a specific, non-mainstream usage. Because radii is the established plural of radius in geometric contexts, radiuse does not have a single, formal definition in conventional references.

In geometry, the radius is the distance from the center of a circle or sphere to any point on its boundary. The conventional plural is radii; some nontechnical authors may use radiuses as an informal or rare variant, but this usage is generally considered nonstandard in scholarly writing. The term radiuse may occasionally surface in older texts, in online discussions, or in fictional or speculative works where authors introduce a specialized concept or parameter named radiuse, but such meanings are not universally accepted.

Etymology for the root radi(us) traces to Latin radius, meaning spoke or ray, with English adaptations forming variants such as radius, radii, and, rarely, radiuses. Because radiuse lacks a stable, agreed-upon definition in established sources, readers are advised to consult the specific text where the term appears to determine its intended meaning.
