genitivsingulus

Genitivsingulus is a Latin grammatical term referring to the genitive singular case of a noun. The genitive case in Latin, like in many other languages, primarily indicates possession, origin, or a part of something. For example, in the phrase "liber pueri" (the book of the boy), "pueri" is the genitivsingulus of the noun "puer" (boy), showing that the book belongs to the boy.

The genitivsingulus is formed by specific endings that are added to the stem of the noun, which vary depending on the noun's declension. Latin nouns are typically categorized into five declensions, and each declension has its own set of genitive singular endings. For instance, in the first declension, the genitive singular often ends in "-ae" (e.g., rosa, rosai - of the rose). In the second declension, it usually ends in "-i" (e.g., dominus, domini - of the master).

Beyond possession, the genitivsingulus can express various other relationships. It can denote the object of certain verbs or prepositions, indicate a partitive sense (e.g., "multum pecuniae" - much money, where "pecuniae" is the genitivsingulus of "pecunia"), or express description or quality. Understanding the genitivsingulus is crucial for accurately translating and comprehending Latin texts, as its function is often determined by its context within a sentence.
