What is the interrogative pronoun?

The interrogative pronoun, used in English as who/whose/whom/what, asks for the identity of something or someone. In Latin, we use the interrogative pronoun quis, quid. Like all other pronouns in Latin, we need to decline it based on the gender, case, and number. Below is a table of the declensions.

Accusativequemquidquōsquāsquae
Ablativequōquōquibusquibusquibus

The pronoun is used like so:

quid vidēs? — What did you see? quis consilium habet? — Who has a plan?

This pronoun is similar but distinct in both forms and usage to the relative pronoun. .
