List of Second Declension Latin Nouns

Latin Second Declension Nouns

Almost all second declension nouns are either Masculine or Neuter.
Neuter nouns of the 2nd declension end in "-um" in the nominative singular, e.g. aurum (gold), beneficium (kindness), donum (gift).
Masculine nouns of the 2nd declension end in either "-us" in the nominative singular, e.g. amicus (friend), cibus (food) or else they end in "-r", e.g. puer (boy), ager (field).
Regardless of gender, second declension nouns can be easily identified with the "-i" ending in the genitive singular (the 2nd part of the dictionary entry).
