interagisce

Interagisce is the third-person singular present indicative form of the Italian verb interagire, meaning to interact or to act in relation to someone or something. It is used to describe actions where a subject engages with other people, systems, or elements. Examples include phrases like “lui interagisce con gli altri” (he interacts with others) or “il software interagisce con l’utente” (the software interacts with the user). The form also appears in formal address with Lei: “Lei interagisce con il team.”

Etymology and meaning: Interagire comes from the Latin interagere, formed from inter- “between, among” and agere “to act.” The word entered Italian with the sense of acting between parties or entities, i.e., to influence or communicate through mutual action.

Usage and context: Interagisce is widely used across domains such as social discourse, technology, and the natural sciences. In everyday language, it often accompanies prepositions like con (“interagisce con”), indicating the entity with which the interaction occurs. In scientific writing, it describes interactions between molecules, particles, or systems, for example, “le molecole interagiscono.” In computing, it can refer to interactions between software and users or between different programs.

Grammar notes: Interagire is a regular -ire verb of the -isc- group in the present tense. The key forms are: io interagisco, tu interagisci, lui/lei interagisce, noi interagiamo, voi interagite, loro interagiscono. The insertion of -isc- distinguishes its present tense from more regular -ire verbs. The meaning remains consistent across tenses, with mood and aspect conveyed through standard Italian conjugation.
