DOM: Lesson - Noun Declensions

Nouns Declensions

Declension is a family of nouns. There are five families of nouns or five declensions in Latin. Nouns may belong to only one declension. Nouns in the same declension share similar case endings. In Latin I, we will focus on First, Second and Third Declensions. Let's examine how to determine the declension of a Latin noun. It begins by understanding how a noun is listed in the dictionary.

Dictionary Entry - Nouns

When you look up a Latin noun in the dictionary, a standard format is provided. Example:

  • puella, puellae, f. - girl

The elements of the dictionary entry are as follows:

  • Item 1: Latin Nominative Singular (puella)
    • The nominative singular form is the basic form of the noun
  • Item 2: Latin Genitive Singular (puellae)
    • The genitive singular form is used to identify a noun's declension and provides the noun base.
  • Item 3: Abbreviated Gender (f. = feminine)
    • There are three genders of Latin nouns:
      • masculine - abbreviated m.
      • feminine - abbreviated f.
      • neuter - abbreviated n.
  • Item 4: English Definition (girl)
    • The definition is the meaning of the noun in English

Let's take a look at a few more examples:

Dictionary Entry Examples
Nominative Singular Genitive Singular Gender Definition
raeda raedae f. (feminine) carriage
carrus carri m. (masculine) cart
plaustrum plaustri n. (neuter) wagon
