[602]. fidēs is declined like rēs; it has once a genitive fidēs (Plaut.). For rēī, reī, or re͡i, and fidēī, fideī, or fide͡i, see [127, 4]. diēs has rarely a genitive diēs (Enn.) or diī (Verg.). spēs has only the genitive and dative spe͡i in verse. A genitive or dative in -ē is sometimes found: as, rē, diē, fidē.
[603]. A few cases of other words sometimes follow this class ([401]): as, plēbēs ([524]), commons, G. plēbe͡i or plēbī; famēs ([524]), hunger, Ab. always famē; requiēs ([477]), rest, G. requiē (Sall.), Ac. requiem, Ab. requiē; tābēs ([523]), waste, Ab. tābē, *contāgēs, contact, Ab. contāgē (Lucr.), &c.
[604]. (2.) Stems of the second class are formed by the suffix -iē- or -tiē-, and have three or more syllables.
This class, which is parallel to stems in -iā-, has usually no genitive, dative, or plural. Many stems, especially those in -tiē-, have also a collateral form in -iā-, and the genitive and dative, when used at all, are commonly from a stem in -iā-.
[605]. Stems in -ē- of the second class are declined as follows:
lūxuriēs, extravagance, stem lūxuriē-, F.
Nom. lūxuriēs, Acc. lūxuriem, Abl. lūxuriē.
[606]. A few examples of the genitive of these stems are found: as, perniciī, perniciēs, or perniciē, ruin (Cic.); rabiēs, fury (Lucr.); aciē, edge of battle (Sall., Caes., auct. B. Afr.), faciē, make (Plaut., Lucil.), speciē, looks (Caes.); aciēī (auct. B. Afr.). And a very few of the dative: as, aciēī twice (Caes.); perniciēī, perniciī (Nep.); perniciē (Liv.).
[607]. ēluviēs, offscouring, wash, has the nominative of the plural, and glaciēs, ice, has the accusative of the plural. Five words only have the nominative and accusative plural:
seriēs, aciēs, row, edge,
