experior

Experior is a Latin deponent verb of the fourth conjugation, meaning primarily “to experience,” “to test,” or “to attempt.” As a deponent, it uses passive forms while conveying active meanings. The principal parts are experior, experiri, expertus sum. The present indicative form is experior (I experience or I test); imperfect is experiebar; future is experiar; and the perfect is expertus sum.

In classical Latin, experior denotes undergoing experience, making an attempt, or testing something, often with nuances of trial or discovery. It governs expressions such as experiri aliquid (to try something) and can appear in constructions that report experience, testing, or the act of experiencing events or sensations.

Etymology and related terms: experior shares its root with expertus (experienced) and with the noun experientia (experience). In English, related words such as experience and experiment derive from the same family of Latin forms; experiment, in particular, comes from experimentum, formed from experiri plus the suffix -mentum.

Modern usage: Beyond Latin grammar, Experior appears as a proper name or brand in contemporary contexts, including companies, products, and programs. Such uses are branding choices and are not tied to the verb’s classical grammatical sense.
