Book Nav
main

92. The following peculiarities in case forms of the 4th Declension require notice.

a. A genitive singular in (as of the 2nd declension) sometimes occurs in nouns in -tus.

senātus, gen. senātī (regularly senātūs)

b. In the genitive plural -uum is sometimes pronounced as one syllable, and may then be written -um.

currum (Aen. 6.653) for curruum

c. The dative and ablative plural in -ŭbus are retained in partus and tribes, regularly in artus and lacus, and occasionally in other words; portus and specus have both -ubus and -ibus.

d. Most names of plants and trees, and colus (distaff) also have 2nd declension forms.

fīcus fig, gen. fīcūs or fīcī

e. An old genitive singular in -uis or -uos and an old Genitive plural in -uom occur rarely.

senātuis, senātuos
fluctuom

f. The ablative singular ended anciently in -ūd (cf. § 43, Note 1): magistrātūd.

93. Domus [(f.) house] has two stems ending in u- and o-. Hence it shows forms of both the 4th and 2nd declensions.

Paradigm for 4th declension feminine noun Domus [house]

Note 1— The Locative is domī (rarely domuīat home.

Note 2— The Genitive domī occurs in Plautus; domōrum is late or poetic.
