fonctionnes

Fonctionnes is the second-person singular present indicative form of the French verb fonctionner. The verb means to operate, to work, or to be functional. As a present-tense form, fonctionnes is used when addressing someone informally (tu) about how something operates.

In use, the phrase describes the operation of devices, systems, or processes. Examples include questions like "Comment ça fonctionne ?" (How does this work?) and statements such as "Cela fonctionne bien" (That works well). The form fonctionnes is most common in direct speech or informal writing, for example in "Tu fonctionnes correctement ?" or in "Dis-moi comment tu fonctionnes."

Etymology and related forms: the verb originates from the noun fonction, which denotes a function or role and comes from Latin functio, meaning performance or execution. The verb is part of a family that includes fonctionner, fonction, and related terms describing how things operate or perform their tasks. Other common tense forms include je fonctionne, il fonctionne, nous fonctionnons, vous fonctionnez, ils fonctionnent.

Notes on usage: while fonctionnes is tied to the informal tu form, the same root appears across tenses and moods, such as "fonctionnons" (let us function), "fonctionnerez" (you will function), or "fonctionnerait" (would function). In everyday French, phrases about operation typically use the impersonal form cela fonctionne or Comment cela fonctionne, rather than focusing on the tu form.
