demonstravi

Demonstravi is a Latin verb form, serving as the first-person singular perfect active indicative of the verb demonstrare, which means to show or to demonstrate. As a perfect tense form, demonstravi conveys a completed action in the past, typically translated as “I demonstrated” or “I showed.”

Formation and meaning: demonstrare belongs to the first conjugation. The standard formation of the perfect active first person singular adds the suffix -avi to the stem demonstr- (from demonstrare), yielding demonstravi. The form is used in narrative and expository Latin to recount actions that have been completed, often with a direct object specifying what was shown or proven.

Usage in context: Demonstravi commonly appears in classical Latin prose and poetry when the speaker asserts that a particular point, fact, or object was shown or established. It takes an accusative object to indicate what was demonstrated, for example causam (“the cause”), rem (“the matter”), or modum (“the method”). The subject is often implied (ego) but may be stated for emphasis.

Relation to related forms: Demonstravi is part of a broader paradigm that includes present forms like demonstro (I show), imperfect forms such as demonstrabam, and the supine or participial forms used to form passive and non-finite constructions. Other Latin verbs with similar perfect endings follow the same pattern, making demonstravi an example of the regular -are verb perfect.

Notes: In Latin grammars, demonstravi is encountered in both historical and didactic texts. Its exact usage depends on stylistic choices and tense sequencing, but it consistently marks a completed act of showing or proving.
