saines

Saines is the feminine plural form of the French adjective sain, meaning healthy or sound. It is used to describe feminine plural nouns, for example, habitudes saines (healthy habits) or aliments saines (healthy foods, when referring to feminine plural nouns). The corresponding feminine singular form is saine, and the masculine forms are sain (singular) and sains (plural). The term derives from Latin sanus via Old French sain; in modern French, sain and its feminine forms agree with the nouns they modify in gender and number.

In English contexts, sain/saine/saines is not a standard word outside discussions of French grammar or quoted French phrases. It may appear in linguistic analyses, bilingual texts, or as part of proper nouns of French origin, such as surnames or toponyms, though it is not a widely recognized place name in major reference works.

The phrase habitudes saines is common in French to describe healthful behavior, including diet, exercise, and daily routines. The concept aligns with the broader idea of promoting physical well-being and balanced living. As a lexical form, sain and its variants are primarily of interest to learners of French or researchers studying language morphology.
