stipulation (n.) Look up stipulation at
1550s, "a commitment or activity to do something" (now obsolete), from Latin stipulationem (nominative stipulatio), noun of action from past participle stem of stipulari "exact a promise, engage, bargain," of uncertain origin. Traditionally said to be from Latin stipula "stalk, straw" (see stipule) in reference to some obscure symbolic act; this is rejected by most authorities, who, however, have not come up with a better guess. De Vaan suggests "the original meaning of the verb was 'to draw/cut straws.' ... The noun stip- must have developed from a concrete object that was used for payments, but the nature of the object is unknown: a certain stalk of a plant? a measure of corn?" Meaning "act of specifying one of the terms of a contract or agreement" is recorded from 1750. Meaning "that which is stipulated or agreed upon" in English is from 1802.
