dimostrata

Dimostrata is the feminine singular past participle of the Italian verb dimostrare, meaning to demonstrate or to prove. It also functions as an adjective meaning demonstrated or proven, and it agrees in gender and number with the noun it modifies (dimostrato, dimostrata, dimostrati, dimostrate).

Usage and grammar

As a participle, dimostrata appears in compound tenses with avere or in passive constructions with essere, though in practice it is often used adjectivally: la tesi dimostrata (the demonstrated thesis) or la tesi è stata dimostrata (the thesis has been demonstrated/proven). In mathematics and science, dimostrata is commonly used to label results that have been proven, such as un teorema dimostrato (a proved theorem) or una proposizione dimostrata (a demonstrated proposition). It can also appear in phrases like dimostrata esistenza (proved existence) or dimostrata correttezza (proved correctness).

Etymology

Dimostrata derives from the verb dimostrare, which in turn comes from Latin demonstrare, meaning to show or prove. The form changes to reflect gender and number in Italian grammar.

Comparison and usage considerations

Dimostrata contrasts with the masculine dimostrato and with the verb form dimostrare itself. In scholarly Italian, authors often prefer dimostrata/dimostrato to indicate the status of a result as proven, rather than using less precise expressions. It should not be used as a noun; its function is adjectival or participial.
