indefinite

Not definite, especially.

Unclear; vague.

Lacking precise limits.

Uncertain; undecided.

Not definite; not defined; not precise; vague: as, an indefinite time, proposition, term, or sensation.

Infinite in number. The term was introduced by Pascal. Descartes distinguished between the indefinite, which has no particular limit, and the infinite, which is incomparably greater than anything having a limit. The distinction is considered as highly important by many metaphysicians.

Specifically, in botany, uncertain in number or too great to be easily counted: for example, the stamens when more than 10, and not clearly in multiples of the ground number of the flower, are said to be indefinite.

In logic, indeterminate in logical quantity; not distinguishing between “some” and “all.”

In grammar, not such as to make definite or determinate the person, thing, place, time, or manner in question: applied to certain adjectives, pronouns, and adverbs, as the indefinite article (see article, 11), any, some, such, anywhere, anyhow, otherwise, and to certain tenses of verbs, as the Greek aorist (which means ‘indefinite’) and the simple past in English.

Not definite; not limited, defined, or specified; not explicit; not determined or fixed upon; not precise; uncertain; vague; confused; obscure
