ēnsis, M., glaive; piscis, M., fish; aedis, F., temple, Pl. house ([418]); vītis, F., vine; and a great many others. Also gender forms of adjectives in -i- ‘of two endings’ ([630]), except the ablative singular, which ends in -ī.

[523]. (2.) Parisyllables in -i- with the nominative in -ēs have their other cases like those of hostis: such are:

caedēs, bloodshed; cautēs, rock; clādēs, disaster; indolēs, native disposition, no Pl.; lābēs, fall; mōlēs, pile; nūbēs, cloud; prōlēs, offspring, no Pl.; pūbēs, young population, no Pl.; rūpēs, crag; saepēs, hedge; strāgēs, slaughter; subolēs, offspring; tābēs, wasting, no Pl., feminines; and some others. Masculine: verrēs, boar; volpēs or vulpēs, fox.

[524]. famēs, hunger, has G. twice famī (Cato, Lucil.), Ab. always famē ([603]), no Pl.; plēbēs, commons, N. also plēbs or plēps, has G. plēbe͡i ([603]), plēbī or plēbis, no Pl.

[525]. (3.) A few stems in -bri-, -cri-, or -tri-, are declined as follows:

imber, shower, stem imbri-, M.

Singular: N. imber, G. imbris, D. imbrī, Ac. imbrem, Ab. imbrī, oftener imbre. Plural: N. imbrēs, G. imbrium, D. imbribus, Ac. imbrīs or imbrēs, Ab. imbribus. So also lunter or linter, F. (M.), tub, boat, ūter, M., leather bag, and venter, M., belly, but with only -e in the Ab.; and the masculine of adjectives in -bri-, -cri-, -tri-, N. -er ([628]); these last have in the Ab. always -ī.

[526]. (4.) Parisyllabic neuters in -i- with the nominative in -e are declined as follows:

[527]. mare has rarely the ablative mare in verse: in the plural only the nominative and accusative are usual; but a genitive marum is once quoted (Naev.), and the ablative maribus is once used by Caesar.
