An indefinite adjective is an adjective formed from an indefinite pronoun.嗯，非限定性形容词。用作代词时是非限定性代词 / indefinite pronoun，用作形容词就是非限定性形容词。
The most common indefinite pronouns are: all, any, anyone, anything, each, everybody, everyone, everything, few, many, nobody, none, one, several, some, somebody, and someone.
When used as adjectives, these are known as "indefinite adjectives". (ref)
非限定性，也就是表示泛指。注意，“所有”，“任何”也是泛指。
法语中与英语类似，常见的 indefinite adjective (adjectif indéfini) 包括 autre, aucun, certain, chaque, divers, différents, maint, même, n'importe, plusieurs, quelque, quelconque, tout, 等等。
tout 貌似是个很麻烦的东西，以后再整理。
