doctrinae

Doctrinae is the plural form of doctrina in Latin, meaning teachings or doctrines. The noun doctrina is a feminine, first-declension word, and in Latin texts its form Doctrinae can function as nominative plural (“the doctrines”) or genitive singular (“of the teaching”), with the intended reading usually determined by context.

In classical Latin, doctrina carried the sense of instruction, knowledge, or systematic learning, and could refer to any body of taught knowledge or a method of teaching. In late antique and medieval Latin, the term increasingly denotes formal or official teachings, especially in theological or philosophical contexts. Phrases such as doctrinae philosophicae (“the doctrines of philosophy”) or doctrinae ecclesiasticae (“the ecclesiastical teachings”) illustrate its usage to describe bodies of doctrine rather than discrete, everyday instruction.

In modern scholarly discussions of Latin language and literature, doctrinae appears as part of analyses of how doctrine and instruction are represented in ancient and medieval texts. It is not a proper noun or a title in itself, but a regular noun that may appear in various grammatical cases, often within discussions of theology, philosophy, or pedagogy. The plural form can underscore multiple doctrines within a unified theoretical framework, or simply reflect the nominative plural subject in a sentence.
