parameteris

Parameteris is a Latin-language form that appears as the genitive singular of the modern loanword parameter. In Latin scientific and scholastic writing, parameteris functions to express possession or relation to a parameter, for example in phrases translated as “the value of the parameter” or “the parameter’s influence.” Because parameter is a relatively new term in many languages, Latin authors occasionally render related phrases with parameteris rather than building entirely with native Latin terms such as mensura or ratio.

In practice, parameteris is encountered primarily in historical or critical editions of Latin texts that discuss mathematical or physical quantities using a Latinized vocabulary. Modern English-language texts do not use parameteris; instead they employ “parameter” and “parameters.” When Latin uses parameter, editors may gloss or translate the surrounding content to aid interpretation.

Etymology and related terms: parameter is a loanword derived from Greek para- “beside” and metron “measure,” adapted through Latin and other languages. The genitive form parameteris follows standard Latin patterns for borrowed terms. Related English terms include parameter, parameters, and parametric; in Latin scholarship, one may also encounter forms such as parametrum in native-adaptation, depending on authorial choice and manuscript tradition.
