immunis

Immunis is a Latin adjective meaning immune, exempt, or protected from liability. The root immun- is related to exemption from duties, and the suffix -is marks gender in Latin adjectives. The form immunis appears in Latin texts to denote exemption from certain obligations, privileges, taxes, or military service. In Roman law and citizen charters, individuals or communities could be described as immunis from taxes or from service; immunitas and related terms describe the state or condition of exemption or immunity.

In historical sources, immunis is frequently found in inscriptions, legal codices, and administrative records, where it qualified persons, places, or groups as exempt from burdens or penalties. The concept of exemption, or immunity, forms a semantic basis for many modern terms; the English word immunity derives from Latin immunitas, with immunis serving as the direct adjective form.

In contemporary usage, immunis is largely encountered in scholarly Latin passages or in discussions of legal history. It is not a standard modern technical term in biology or medicine, where the English word immune and the noun immunity are preferred. Nevertheless, the Latin term continues to appear in translations, glossaries, and comparative law texts to indicate exemption or protection from obligation.
