Notes and Further Info

Masculine second decl. nouns ending in -us in the nominative, like servus above, take the endings -us, -e in the nom. and voc. as in the tables. Nouns not ending thus in the nom take no endings in these two cases singular. All other forms take endings.
An example is puer, -i, boy. Since it does not end in -us, it declines as follows:
Nom and voc sg: puer. All other forms (including nom and voc pl) are formed normally.
