Sororibus

Sororibus is a Latin noun form that serves as the dative plural and the ablative plural of soror, meaning sister. In Latin, the same form marks both cases in the plural, so its function is determined by the surrounding grammar and context.

Grammar and forms: Soror is a 3rd-declension feminine noun. Its full paradigm is: singular — nom soror, gen sororis, dat sorori, acc sororem, abl sorore; plural — nom sorores, gen sororum, dat sororibus, acc sorores, abl sororibus. Therefore sororibus can translate as “to/for the sisters” (dative plural) or “with/ by/ from the sisters” (ablative plural), depending on sentence structure.

Usage: Sororibus occurs in classical and ecclesiastical Latin to refer to female siblings or to address or describe groups of women associated as sisters. For example, donum sororibus dedit means “he gave a gift to the sisters,” where sororibus is the indirect object. With cum sororibus, it can indicate accompaniment, meaning “with the sisters.” In religious contexts, phrases such as sororibus nostris may appear in letters or liturgical texts to refer to “our sisters” in a convent or order.

Context and notes: As a common older Latin form, sororibus appears primarily in texts dealing with family relations or religious communities. It is not a modern noun with separate semantic extensions; its primary value is grammatical and translational, indicating plural indirect object or instrumental/locative relationships with sisters.
