Today's word is EXPENDO, a third-conjugation verb: expendo, expendere, expendi, expensum.
Latin meaning and usage: Literally pendere means to "cause to hang down, to suspend," and so it comes to mean "to weigh" from the use of scale balances to measure weight. So expendere means "to weigh out, weigh out money in payment, pay." The participle, expensum, is used substantively to mean "money paid." The Latin verb can also be used metaphorically to mean "weigh mentally, value, evaluate."
Latin word formation: The verb is a compound, with the prefix ex- and the root pendere.
English cognates and derivatives: We get the English words "expend" and "expense" from this verb, along with "expensive."
