Demonstratus

Demonstratus is a Latin participle meaning "shown" or "demonstrated." In Latin grammar, it is the perfect passive participle of the verb demonstrare, and its form changes to agree with gender and number (for example, demonstratus in masculine singular, demonstrata in feminine or neuter forms). It functions as an adjective or as part of a compound expression in Latin texts.

Etymology and basic usage

The term derives from demonstrare, "to show" or "to demonstrate," with the suffix -atus forming a past participle. As an adjective, demonstratus can modify a masculine noun, with demonstrata and demonstratum corresponding to feminine and neuter nouns, respectively. In classical and medieval Latin, participles like demonstratus were used to describe things that had been shown, proven, or demonstrated within a given argument or description.

Applications in taxonomy and scholarly writing

In biological nomenclature, Latin adjectives used in species names must agree in gender with the genus. Demonstratus, if used as a species epithet, would typically be treated as a masculine form and would describe a trait of the organism that has been demonstrated or observed. However, demonstratus is not a common or widely established epithet in modern taxonomic practice, and any usage would be determined by the relevant genus name and grammatical agreement.

Other textual uses

Beyond biology, demonstratus appears in scholarly Latin passages to indicate that a proposition, demonstration, or finding has been shown or proven. It may appear in legal, philosophical, or theological Latin writings in phrases where a point is described as demonstrated.
