38 LESSON XII NOUNS IN -IUS AND -IUM 87. Nouns of the second declension in -ius and -ium end in -ī in the genitive singular, not in -iī, and the accent rests on the penult; as, fīlī from fīlius (son), praesi’dī from praesi’dium (garrison).

88. Proper names of persons in -ius, and fīlius, end in -ī in the vocative singular, not in -ĕ, and the accent rests on the penult; as, Vergi’lī, O Vergil; fīlī, O son.


 * a. Observe that in these words the vocative and the genitive are alike.

89. praesidium (base praesidi-), n., garrison fīlius (base fīli-), m., son

The plural is regular. Note that the -i- of the base is lost only in the genitive singular, and in the vocative of words like fīlius.

Decline together praesidium parvum; fīlius bonus; fluvius longus, the long river; proelium clārum, the famous battle.
