Word History

Etymology

borrowed from Latin, "gain, profit, saving, short cut, abridgement, summary," from com- com- + pendere "to weigh, have a weight of, pay (out), estimate, consider" + -ium, suffix forming nouns from compound verbs — more at pendent

Note: Latin compendium would appear to have been formed from compendere, presumably "to weigh together," but the only evidence for such a verb is its citation by varro to account for the etymology of compendium.
