The Latin name for bear, used in scientific classification and taxonomy.
From Latin ursus (a bear), possibly from an Indo-European root meaning 'brown'; it's the genus name for brown bears and remains standard in scientific nomenclature.
Ursus is one of those Latin words that stuck around in English science rather than getting replaced, so it's still used in formal species names like 'Ursus arctos' (brown bear)—showing how scientific Latin gives animals a kind of formal, official identity separate from their common names.
