This regex matches the French word for bear and its variants: 'ours' (bear), 'ourson' (bear cub), 'ourse' (female bear), and their plural forms 'oursons' and 'ourses'. It is designed for finding bear-related terms in French texts, such as the fairy tale 'Boucle d'or' (Goldilocks). The pattern allows an optional suffix 'on' or 'e' and an optional 's' for plurals.
