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

It were to be wished that . . . men would leave off that indefinite
way of vouching, "the chymists say this," or "the chymists affirm
that."
Boyle.
The time of this last is left indefinite.
Dryden.
2. Having no determined or certain limits; large and unmeasured, though
not infinite; unlimited; as, indefinite space; the indefinite extension
of a straight line.
Though it is not infinite, it may be indefinite; though it is not
boundless in itself, it may be so to human comprehension.
Spectator.
