n., adj. equal in value, force or meaning.
EQUIVALENT. Of the same value. Sometimes a condition must be literally accomplished in forma specifica; but some may be fulfilled by an equivalent, per oequi polens, when such appears to be the intention of the parties; as, I promise to pay you one hundred dollars, and then die, my executor may fulfill my engagement; for it is equivalent to you whether the money be paid to you b me or by him.
