§98. Case-Forms in the Fifth Declension
The following peculiarities require notice:—
a. Of nouns of the fifth declension, only diēs and rēs are declined throughout. Most want the plural, which is, however, found in the nominative or accusative in aciēs, effigiēs, ēluviēs, faciēs, glaciēs, seriēs, speciēs, spēs.1
b. The Locative form of this declension ends in -ē. It is found only in certain adverbs and expressions of time:—
| hodiē, to-day; | diē quārtō (old, quārtī), the fourth day; |
| perendiē, day after to-morrow; | prīdiē, the day before. |
c. The fifth declension is closely related to the first, and several nouns have forms of both: as, māteria, -iēs; saevitia, -iēs. The genitive and dative in -ēī are rarely found in these words.
d. Some nouns vary between the fifth and the third declension: as, requiēs, satiēs (also satiās, genitive -ātis), plēbēs (also plēbs, genitive plēbis), famēs, genitive famis, ablative famē.
