gazeuse

Gazeuse is the feminine form of the French adjective gazeux, meaning containing or filled with gas. It is most commonly used to describe liquids with dissolved gas, especially carbon dioxide. In everyday French, eau gazeuse denotes sparkling water, and boissons gazeuses refers to carbonated soft drinks.

Beyond beverages, gazeuse can describe substances in a gaseous state in scientific or technical contexts; the corresponding masculine form gazeux appears in phrases such as l'état gazeux (the gaseous state). The feminine form agrees with a feminine noun, as in une substance gazeuse.

Labeling and variants are common in labeling and marketing. In the beverage industry, terms include eau gazeuse, eau minérale gazeuse, and eau pétillante. The choice of term can reflect nuances: gazeuse emphasizes the presence of dissolved gas, while pétillante highlights the lively effervescence. Natural carbonation is often described as eau gazeuse naturelle or eau minérale pétillante naturelle.

Etymology-wise, gazeuse derives from gaz (gas) with the French adjective suffix -euse, indicating a feminine form. The pair gazeux/gazeuse is used across domains, including gastronomy, hydrology, and physics, to indicate gas content or a gaseous state. In summary, gazeuse is a gendered French descriptor for substances that contain gas or exhibit sparkling qualities.
