[642]. The adjective mīlle, thousand, is not declined. The substantive has in the singular only N. Ac. Ab. mīlle, or Ab. mīllī; plural: N. and Ac. mīllia (mīlia), G. mīllium (mīlium), D. and Ab. mīllibus (mīlibus).
[643]. Ordinals, as prīmus, first, and distributives, as bīnī, two each, are declined like bonus ([613]). But distributives seldom have a singular, and often have the genitive plural -ū̆m ([462]): as, bīnū̆m.
[THE PRONOUN.]
[(A.) THE PERSONAL AND REFLEXIVE PRONOUN.]
[644]. The pronoun of the first person, ego, I, of the second person, tū, thou, and the reflexive pronoun, suī, sē, himself, herself, itself, themselves, are declined as follows:
| ego, I | tu, thou | sui, self | |||
|---|---|---|---|---|---|
| Sing. | Plur. | Sing. | Plur. | Sing. & Plur. | |
| Nom. | ego | nōs | tū | vōs | |
| Gen. | meī | nostrum, -trī | tuī | vestrū̆m, -trī | suī |
| Dat. | mihī̆, mi | nōbīs | tibī̆ | vōbīs | sibī̆ |
| Acc. | mē | nōs | tē | vōs | sē |
| Abl. | mē | nōbīs | tē | vōbīs | sē |
[645]. The nominatives ego and tū, and the accusatives mē, tē and sē, have no case ending. The last vowel of ego is rarely long in Plautus, long or short in Lucilius. The nominative ego has a different stem from that of its other cases, and the plurals of ego and tū have a different stem from that of the singular.
[646]. meī, tuī, and suī, which are often monosyllables in old verse, were originally the genitive of the neuter possessives, used substantively. An old genitive mīs is quoted, and tīs occurs rarely in Plautus.
[647]. The relation of the ending -bīs in vōbīs to -bī̆ in tibī̆ may be due to analogy with illīs, illī. nōbīs is formed after vōbīs.
[648]. In old Latin, the ablative is mēd, tēd, sēd ([426]), which forms are also used irrationally for the accusative. But by Terence’s time the -d was no longer used ([143]).
