issage

Issage is a French noun-forming suffix used to derive nouns from verbs, indicating an action, its process, or the result of the action. It is a productive variant within the broader system of French suffixes that form nouns from verb bases and is especially common in technical, industrial, and crafts vocabulary. The suffix often carries a neutral to objective sense, focusing on the activity rather than a person performing it.

Common examples illustrate its use. Polissage (from polir) refers to the act of polishing or the polish produced. Lissage (from lisser) denotes smoothing or straightening, as in hair or surfaces. Tissage (from tisser) means weaving or the resulting woven fabric. Vissage (from visser) designates the act of screwing or the screwed assembly in mechanical or construction contexts. These terms show how -issage creates concrete process nouns that are readily used in manuals, specifications, and everyday technical speech.

Morphologically, -issage forms regularly with a wide range of verb bases, producing nouns that are often semantically close to the English -ing or -ation forms in describing a process. In many cases the resulting noun names a repetitive, ongoing, or completed activity, suitable for describing methods, phases of production, or finishes.
