The distinction between que ＜ _quĕm_, que quez ＜ _quĭd_, and que ＜
_quæ_ could not be maintained; we have, then, simply three forms: a
nom. sg. or pl. qui, a nom.-acc. sg. or pl. quẹ (quẹz), a dat. sg. or
pl. cüi (sometimes written _qui_).
134. We have also _qualis_, which came to be inflected like fezẹls:
see § 103, (2); the feminine singular, however, often dropped its -s,
and sometimes took the ending -a (cal, cala). _Quīnam_ apparently
became quina, which, understood as a feminine form, developed a
masculine, quin. There seems to have been also a ✱_quīniam_ (cf.
_quŏniam_?), which gave quinh, quinha. Cf. D. Behrens in the
_Zeitschrift für französische Sprache_, XVII, ii, 67-8, footnote. The
phrase _de ŭnde_ became dọnt, dọn, which was often used with the
meaning ‘of which’, ‘of whom’.
135. (1) In Provençal the interrogative pronouns are: qui, ‘who’ or
‘whom’; que quez, ‘what’; cüi, ‘to whom’ or ‘whom’, ‘to what’ or
‘what’ (obj.); cals (either alone or preceded by the definite article,
inflected as in § 134), ‘which’; quin quinh, quina quinha, ‘which’.
Cals is used also as an adjective.
(2) The relative pronouns are: qui, ‘one who’, indefinite (used also,
in early texts and in southwestern Languedoc, as the regular relative
pronoun for persons); que quez, ‘who’ or ‘whom’, ‘which’; cüi, ‘whom’,
‘which’ (generally used as indirect object of a verb, or after a
preposition); lo cals (inflected as in § 134), ‘who’ (‘whom’), ‘which’;
don dont, ‘of which’, ‘of whom’.
