110. Adjectives of the 1st and 2nd Declensions (ā- and o- stems) are declined in the masculine like servus, puer, or ager; in the feminine like stella; and in the neuter like bellum.
The regular type of an adjective of the 1st and 2nd Declensions is bonus, -a, -um, which is declined below:
|NOM. provinces (-quos)||propinqua||propincum (-quom)|
|GEN. propinquī||propinquae||propinquī, etc.|
But most modern editions disregard this principle.
a. The Genitive Singular masculine of adjectives in -ius ends in -iī, and the Vocative in -ie; not in -ī, as in nouns (cf. § 49. b-c).
Lacedaemonius, -iī, -ie
Note— meus (my) has the vocative masculine mī (cf. § 145).
