CEN: Lesson - Noun Endings Charts

Noun Endings Charts

Below is a set of charts containing all the previous case endings, but now including the two new cases: genitive and dative. With these two cases, we have now explored all six of the main noun cases in Latin: Nominative, Genitive, Dative, Accusative, Ablative and Vocative.

This is the complete set of noun endings, so be sure to use this order from now on!

Noun Endings - 1st Declension
Case Singular Plural
Nominative a ae
Genitive ae arum
Dative ae is/abus*
Accusative am as
Ablative a is/abus*
Vocative a ae

Nota bene:

  • 1st declension nouns are mostly feminine, but there are some masculine nouns. The masculine nouns use the same endings as the feminine.
  • *Some feminine nouns, like dea and filia, share a noun base with a 2nd declension masculine noun (deus, filius). The feminine nouns will end with -abus (deabus, filiabus) in the dative and ablative plural instead of -is to avoid confusion with the masculine nouns (deis, filiis).
Noun Endings - 2nd Declension
Case Masculine Singular Masculine Plural Neuter Singular Neuter Plural
Nominative us (er, ir) i um a
Genitive i orum i orum
Dative o is o is
Accusative um os um a
Ablative o is o is
Vocative Same as Nom* i um a

Nota Bene:

  • *Remember: the vocative form will be the same as the nominative form, with just one exception: 2nd declension masculine nouns ending in us (or ius):
    • -us changes to -e (Decime from Decimus)
    • -ius changes to -i (Claudi from Claudius)
Noun Endings - 3rd Declension
Case M/F Singular M/F Plural Neuter Singular Neuter Plural
Nominative varies** es varies** a
Genitive is um*** is um***
Dative i ibus i ibus
Accusative em es Same as Nom a
Ablative e ibus e ibus
Vocative Same as Nom es Same as Nom a

Nota Bene:

  • **Varies is not an ending, but a note to remind you that 3rd declension has no set nominative singular ending. Instead, the nominative singular will be the first word listed in the dictionary entry. You will need to take special note of the nominative form when learning the vocabulary for a lesson.
  • ***Some special 3rd declension nouns (called i-stem) end in -ium in the genitive plural. These will be noted in the vocabulary lists and discussed in detail in a future lesson.
