a. The adverb -cumque (-cunque) (cf. quisque) added to the relative makes an indefinite relative, which is declined like the simple word: as, quícumque, quaecumque, quodcumque, whoever, whatever; cuiuscumque, etc.
NOTE: This suffix, with the same meaning, may be used with any relative: as, quáliscumque, of whatever sort; quandócumque (also rarely quandóque), whenever; ubicumque, wherever.
b. In quisquis, whoever, both parts are declined, but the only forms in common use are quisquis, quidquid (quicquid) and quóquó.
NOTE 1: Rare forms are quemquem and quibusquibus; an ablative quíquí is sometimes found in early Latin; the ablative feminine quáquá is both late and rare. Cuicui occurs as a genitive in the phrase cuicui modí, of whatever kind. Other cases are cited, but have no authority. In early Latin quisquis is occasionally feminine.
NOTE 2: Quisquis is usually substantive, except in the ablative quóquó, which is more commonly an adjective.
c. The indefinite pronouns quídam, a certain (one); quívís, quílibet, an[QUERY] you please, are used both as substantives and as adjectives. The first par[QUERY] is declined like the relative quí, but the neuter has both quid- (substantive) and quod- (adjective): -
| quídam | quaedam | quiddam (quoddam) | |
| quívís | quaevís | quidvís (quodvís) |
d. The indefinite pronouns quispiam, some, any, and quisquam, any at al are used both as substantives and as adjectives. Quispiam has feminine qua[QUERY]piam (adjective), neuter quidpiam (substantive) and quodpiam (adjective) the plural is very rare. Quisquam is both masculine and feminine; the neuter is quidquam (quicquam), substantive only; there is no plural. Úllu[QUERY] -a, -um, is commonly used as the adjective corresponding to quisquam.
e. The indefinite pronoun aliquis (substantive), some one, aliquí (adjective), some, is declined like quis and quí, but aliqua is used instead of aliqua except in the nominative plural feminine: -
| SINGULAR | |||
| NOM. | aliquis (aliquí) | aliqua | aliquid (aliquod) |
| GEN. | alicuius | alicuius | alicuius |
| DAT. | alicui | alicui | alicui |
| ACC. | aliquem | aliquam | aliquid (aliquod) |
| ABL. | aliquó | aliquá | aliquó |
|
| PLURAL |
NOM. | |
| GEN. | aliquórum | aliquárum | aliquórum |
| DAT. | aliquibus | aliquibus | aliquibus |
| ACC. | aliquós | aliquás | aliqua |
| ABL. | aliquibus | aliquibus | aliquibus |
NOTE: Aliquí is sometimes used substantively and aliquis as an adjective.
f. The indefinite pronoun ecquis (substantive), whether any one, [QUERY] (adjective), whether any, is declined like aliquis, but has either ecquae ecqua in the nominative singular feminine of the adjective form.
NOTE: Ecquis (ecquí) has no genitive singular, and in the plural occurs in nominative and accusative only.
g. The enclitic particle -que added to the interrogative gives a universe as, quisque, every one; uterque, each of two, or both. Quisque is decline like the interrogative quis, quí: - substantive, quisque, quidque; adjective, quíque, quaeque, quodque.
In the compound únusquisque, every single one, both parts are declined (genitive uníuscuiusque), and they are sometimes written separately and even separated by other words: -
h. The relative and interrogative have rarely a possessive adjective cuius (-a, -um), older quoius, whose; and a patrial cuiás (cuiát-), of what country.
i. Quantus, how great, quális, of what sort, are derivative adjectives from the interrogative. They are either interrogative or relative, corresponding respectively to the demonstratives tantus, tális (§ 152). Indefinite compounds are quantuscumque and quáliscumque (see § 151. a).
