nites,
quis-forms and quid-forms are mostly used as substantives,
qui-forms and quod-forms as adjectives.

_b._ The indefinites /quis\ and /qui\ never stand first in a clause,
and are rare excepting after /si\, /nisi\, /ne:\, /num\ (as, si
quis, _if any one_; si quid, _if anything_; nisi quis, _unless
some one_). Generally /aliquis\ and /aliqui\ are used instead.

_c._ The forms /qua\ and /aliqua\ are both feminine nominative
singular and neuter nominative plural of the indefinite adjectives
/qui\ and /aliqui\ respectively. How do these differ from the
corresponding forms of the relative /qui\?

_d._ Observe that /qui:dam\ (qui: + -dam) is declined like /qui:\,
except that in the accusative singular and genitive plural /m\ of
/qui:\ becomes /n\ (cf. Sec. 287.a): /quendam\, /quandam\,
/quorundam\, /quarundam\; also that the neuter has /quiddam\
(substantive) and /quoddam\ (adjective) in the nominative and
accusative singular. /Qui:dam\ is the least indefinite of the
indefinite pronouns, and implies that you could name the person or
thing referred to if you cared to do so.

_e._ /Quisquam\ and /quisque\ (substantive) are declined like
/quis\.

_f._ /Quisquam\, _any one_ (quicquam or quidquam, _anything_),
is always used substantively and chiefly in negative sentences. The
corresponding adjective _any_ is /u:llus, -a, -um\ (Sec. 108).
