þeirri
þeirri is a grammatical form found in Old English. It is the dative plural form of the third-person singular feminine pronoun, which corresponds to modern English "her" or "she." In Old English, pronouns changed their endings depending on their grammatical case, number, and gender. The dative case typically indicates the indirect object of a verb or the object of certain prepositions. Therefore, "þeirri" would be used in a sentence where "her" or "she" is the indirect object, or when the pronoun is governed by a dative-governing preposition. For instance, if a sentence meant "He gave her a gift," the Old English equivalent might use "þeirri" to represent "her." Similarly, if a sentence meant "She spoke about her," "þeirri" could function in that context. Understanding these inflected forms is crucial for comprehending Old English grammar and accurately translating the language. The pronoun system in Old English was significantly more complex than in Modern English, with many more distinct forms to denote grammatical function.
