Forms

impendium n (genitive impendiī or impendī); second declension[1] It is also spelled inpendium.[2][3] Some inscriptions treat it as a feminine.[4]

Etymology

It is from Latin impendō (“to pay out, spend”) + -ium.[2][3][1] The TLL compares compendium (“saving”) and dispendium (“loss”).[3] The verb is in- with pendō (“to weigh, pay”), which de Vaan traces to Proto-Italic *pend-e/o- (“to hang, weigh”) and Proto-Indo-European *(s)pend-e/o- (“to spin”).[5]

Earliest recorded meaning

Köbler dates it from Plautus.[6] Varro explains it as the interest that joins sums together, as against the capital.[2]

Semantic evolution

It is money laid out, expense or payment, most often in the plural, and Lewis & Short compare sumptus and impensa.[4] Cicero speaks of a man who made a profit without expense, and Varro uses it of interest on a loan.[4][2] Figuratively it is cost or sacrifice, as Curtius writes that a huge victory cost so little.[2] Church Latin glosses it charge, expense.[7]
