How many declensions are used in Latin grammar?

In Latin grammar, there are five declensions. Each declension has its own set of endings and rules for conjugating nouns, which indicate the noun's case (such as nominative, accusative, genitive, dative, and ablative), number (singular or plural), and gender (masculine, feminine, neuter).

The first declension primarily includes feminine nouns and follows a characteristic pattern in its endings, while the second declension typically includes masculine and neuter nouns. The third declension is noted for the various forms and includes nouns of all genders. The fourth declension predominantly contains masculine and neuter nouns, and the fifth declension is largely made up of feminine nouns. Understanding these declensions is essential for translating Latin effectively, as it helps to identify not just the function of a noun within a sentence, but also how it relates to other words. Each declension contributes to the overall structure and richness of Latin grammar, making five the definitive and accurate count.
