rythme

Rythme is masculine. While it does derive from Latin "rhythmus" and ultimately from Greek "rhythmos" (ῥυθμός), the explanation oversimplifies the gender assignment. In French, the masculine gender of "rythme" is better explained by the word's ending in "-e" combined with its Latin masculine origin, but French does not consistently preserve Latin grammatical genders. The word is masculine primarily because it was established as such in French usage, not as a systematic rule of retaining Latin genders, since many Latin masculine nouns become feminine in French (e.g., "murus" → "mur" remains masculine, but "amicus" → "ami" is masculine while Latin "rosa" → "rose" is feminine in French).
