[*] 98. 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.|
[*] Note.--In the genitive and dative -ēī (-ĕī) was sometimes contracted into -ei : as, tribūnus plēbei , tribune of the people ( plēbēs ). Genitives in -ī and -ē also occur: as, “ diī ” (Aen. 1.636) , plēbī-scītum, “ aciē ” (B. G. 2.23) . A few examples of the old genitive in -ēs are found (cf. -ās in the first declension, § 43. b). The dative has rarely -ē, and a form in -ī is cited.
