1. In the Indefinite Pronouns, only the pronominal part is declined. Thus: Genitive Singular alicūjus, cūjuslibet, etc.
2. Note that aliquī has aliqua in the Nominative Singular Feminine, also in the Nominative and Accusative Plural Neuter. Quī has both qua and quae in these same cases.
3. Quīdam forms Accusative Singular quendam, quandam; Genitive Plural quōrundam, quārundam; the m being assimilated to n before d.
4. Aliquis may be used adjectively, and (occasionally) aliquī substantively.
5. In combination with nē, sī, nisi, num, either quis or quī may stand as a Substantive. Thus: sī quis or sī quī.
6. Ecquis, any one, though strictly an Indefinite, generally has interrogative force. It has both substantive and adjective forms,—substantive, ecquis, ecquid; adjective, ecquī, ecquae and ecqua, ecquod.
7. Quisquam is not used in the Plural.
8. There are two Indefinite Relatives,—quīcumque and quisquis, whoever. Quīcumque declines only the first part; quisquis declines both but has only quisquis, quidquid, quōquō, in common use.
