English Synonyms and Antonyms

  1. unfathomable

    Infinite (Latin in, not, and finis, limit) signifies without bounds or limits in any way, and may be applied to space, time, quantity, or number. Countless, innumerable, and numberless, which should be the same as infinite, are in common usage vaguely employed to denote what it is difficult or practically impossible to count or number, tho perhaps falling far short of infinite; as, countless leaves, the countless sands on the seashore, numberless battles, innumerable delays. So, too, boundless, illimitable, limitless, measureless, and unlimited are loosely used in reference to what has no apparent or readily determinable limits in space or time; as, we speak of the boundless ocean. Infinite space is without bounds, not only in fact, but in thought; infinite time is truly eternal. Compare synonyms for ETERNAL.

    absolute, boundless, countless, eternal, illimitable, immeasurable, infinite, innumerable, interminable, limitless, measureless, numberless, unbounded, unconditioned, unlimited, unmeasured

    bounded, brief, circumscribed, evanescent, finite, limited, little, measurable, moderate, narrow, restricted, shallow, short, small, transient, transitory
