The second declension
Now that we’ve learnt the first declension (see Lesson 1 to catch up), we can move onto the next declension. The second declension is mostly masculine, with the only exception being humus, humi (ground/ earth) and has a neuter variation where there is a different NOM and ACC pl ending (ending in ‘a’) and can be remembered by the rhyme ‘please remember every day, neuter plurals end in ”a”’. The endings go as follows:
Singular NOM
serv-us
VOC (-us nouns = -e and -ius = -)
serv-e or -i
ACC
serv-um
GEN
serv-i
DAT
serv-o

Plural NOM

There are two important irregular nouns in the second declension: these are viros (man) and deus (god). In the plural from of deus, the ‘e’ can fall down in the NOMINATIVE, DATIVE, ABLATIVE.
