The meaning seems to have been influenced in Latin by dispar "unequal, unlike" (from apparently unrelated Latin par "equal, equal-sized, well-matched"). Related: Disparately; disparateness. As a noun, "one of two or more things or characters so unlike that they cannot be compared with each other," 1580s.

disparage (v.)

Also from late 14c. as "injure or dishonor by a comparison," especially by treating as equal or inferior to what is of less dignity, importance, or value. Sense of "belittle, undervalue, criticize or censure unjustly" is by 1530s. Related: Disparaged; disparaging; disparagingly.

dispatcher (n.)

"one who dispatches," mid-16c., agent noun from dispatch (v.).

dispatch (v.)

1510s, "to send off, send to a destination," usually implying urgent importance or haste, from Spanish despachar "expedite, hasten" or cognate Italian dispacciare "to dispatch." For first element, see dis-.

The second element apparently has been confused or corrupted, and its exact source and meaning is uncertain. One proposal is that it is Vulgar Latin *pactare "to fasten, fix" or *pactiare. Another says it is Latin -pedicare "to entrap" (from Latin pedica "shackle;" see impeach), and the Spanish and Italian words seem to be related to (perhaps opposites of) Old Provençal empachar "impede." See OED for full discussion.

Meaning "get rid of promptly by killing" is attested from 1520s; that of "attend to, finish, bring to an end, accomplish" is from 1530s. Related: Dispatched; dispatching.

c. 1400, dispellen, "drive off or away," from Latin dispellere "drive apart," from dis- "away" (see dis-) + pellere "to drive, push" (from PIE root *pel- (5) "to thrust, strike, drive"). Since the meaning is "to drive away in different directions" it should not have as an object a single, indivisible thing (you can dispel suspicion, but not an accusation). Related: Dispelled; dispelling.

dispensable (adj.)

1530s, "subject to (ecclesiastical) dispensation, excusable, pardonable," from Medieval Latin dispensabilis, from Latin dispensare "disburse, administer, distribute (by weight)" (see dispense).

Meaning "a container that dispenses in fixed measure" is from 1918.

dispense (v.)

mid-14c., dispensen, "to dispose of, deal or divide out," from Old French dispenser "give out" (13c.), from Latin dispensare "disburse, administer, distribute (by weight)," frequentative of dispendere "pay out," from dis- "out" (see dis-) + pendere "to hang, cause to hang; weigh; pay" (from PIE root *(s)pen- "to draw, stretch, spin").

In Medieval Latin, dispendere was used in the ecclesiastical sense of "grant licence to do what is forbidden or omit what is required" (a power of popes, bishops, etc.), and thus acquired a sense of "grant remission from punishment or exemption from law," hence the use of the English verb in the senses "to do away with" (1570s), "do without" (c. 1600). The older sense is preserved in dispensary. Related: Dispensed; dispensing.

dispensation (n.)

late 14c., dispensacioun, "power to dispose of," also "act of dispensing or dealing out," also "a relaxation of the law in some particular case," from Old French despensacion (12c., Modern French dispensation) and directly from Latin dispensationem (nominative dispensatio) "management, charge," noun of action from past-participle stem of dispensare "disburse, administer, distribute (by weight)" (see dispense). Related: Dispensational.

Theological sense "method or scheme by which God has developed his purposes and revealed himself to man" (late 14c.) is from the use of the Latin word to translate Greek oikonomoia "office, method of administration" (see economy). Hence "particular period during which a religious system has prevailed" (1640s), with Patriarchal, Mosaic, Christian, etc. Also "a particular distribution (for good or ill) by divine providence" (1650s).

The Latin word is glossed in Old English by tostregdan. Intransitive sense of "to separate and move apart in different directions without regularity" is from 1520s.
