satisfacio

Satisfacio is a Latin verb meaning “I satisfy,” derived from satisfacere, “to satisfy” or “to make satisfactory.” It is the first-person singular present active indicative form used in classical and medieval Latin. The verb belongs to the third conjugation with the -io ending, similar to facere, and forms its present tense with a pattern common to -io verbs.

The word is built from satis, meaning “enough,” and facere, meaning “to do/make,” conveying the sense of making something enough or fulfilling a requirement. The noun satisfactio, formed from the same root, denotes “satisfaction” or compliance and has separate uses in legal and philosophical Latin.

In Latin texts, satisfacio could appear in legal, rhetorical, or everyday contexts where one states that one satisfies a condition, obligation, or request. Like other Latin verbs, its forms would shift for person, number, mood, and tense, but the present first-person singular is the most common reference point for the lemma.

Today, satisfacio is primarily of interest to scholars of Latin grammar and philology as an example of an -io verb and of the broader semantics of satisfaction in Latin. It is not a widely used term in modern languages outside academic discussion, where the noun satisfactio and the verb satisfacere are more common.
