VII. INTERROGATIVE PRONOUNS.
[90]. The Interrogative Pronouns are quis, who? (substantive) and quī, what? what kind of? (adjective).
1. Quis, who?
| SINGULAR. | PLURAL. | ||
| MASC. AND FEM. | NEUTER | ||
| Nom. | quis | quid | The rare Plural |
| Gen. | cūjus | cūjus | follows the declension |
| Dat. | cui | cui | of the Relative Pronoun. |
| Acc. | quem | quid | |
| Abl. | quō | quō | |
2. Quī, what? what kind of? is declined precisely like the Relative Pronoun; viz. quī, quae, quod, etc.
a. An old Ablative quī occurs, in the sense of how? why?
b. Quī is sometimes used for quis in Indirect Questions.
c. Quis, when limiting words denoting persons, is sometimes an adjective. But in such cases quis homō = what man? whereas quī homō = what sort of man?
d. Quis and quī may be strengthened by adding -nam. Thus:—
| Substantive: | quisnam, who, pray? quidnam, what, pray? |
| Adjective: | quīnam, quaenam, quodnam, of what kind, pray? |
VIII. INDEFINITE PRONOUNS.
[91]. These have the general force of some one, any one.
