(B)
Interest on money, PROPR., usura, or plur. usurae (what is paid for the use of a borrowed sum; hence “interest,” with reference to the borrower who pays): fenus (the profit on a sum lent; hence “interest,” with reference to the lender who receives or is to receive it): impendium (= usura quod in sorte accedit; Varr., L.L., 5, 36, 50, § 183: all three, also, figuratively). Interest upon interest, anatocismus (ἀνατοκισμόσ, Cic., Att., 5, 21, 11 and 12): usurae usurarum (Cod. Just., 4, 32, 28): 5 per cent, (monthly interest), centesimae quinae: one-half per cent, (monthly) interest = 6 per cent, (annually), semisses usurae: 12 per cent., centesimae usurae (= 1 per cent, per month): 12 per cent, compound interest, centesimae renovato in singulos annos fenore (Cic., Att., 6, 3, 5); or centesimae renovatae quotannis; or centesimae actae cum renovatione singulorum annorum (Att., 6, 1, 5): 12 per cent, at simple interest, centesimae perpetuo fenore or centesimae perpetuae. ☞ The Roman interest being monthly, must be multiplied by 12 to turn it into our method of calculating interest; the asses usurae or centesimae usurae being 1 per cent, monthly = 12 per cent, per annum; lower rates will be expressed by the divisions of the as; thus, 11 percent., deunces usurae; 10, dextantes usurae; 9, dodrantes usurae; 8, besses usurae; 7, septantes usurae; 6, semisses usurae; 5, quincunces usurae; 4, quadrantes usurae; 3, trientes usurae: 2, sextantes usurae; 1, unciae usmae; and ☞ for these other forms occur; e.g., fenus ex...

Georges recommends the retention of the Roman forms, adding in singulos annos, to show that ifis not due every month, but every year: it is better, however, to reduce the yearly to the monthly value, as above. To put out money at interest, pecuniam dare fenori or fenore; ponere in fenore nummos (Hor.): to lend money to anybody at interest, pecuniam alicui dare, pecuniam apud aliquem occupare, with or without fenore: to lend money at a high rate of interest, pecuniam grandi fenore occupare: money on which interest is paid, pecunia fenebris: money on which no interest is paid, pecunia gratuita (if lent); pecunia otiosa (which is not lent, and so brings no interest to the possessor): lending money upon interest, feneratio: to offer anybody money for which he is not to pay any interest, pecuniam alicui gratuitam proponere: to borrow money upon interest, pecuniam sumere or accipere fenore: to borrow money at a low rate of interest, and lend it at a high one, pecunias levioribus usuris mutuari et graviori fenore collocare: to lend anybody money, and take no interest for it, pecuniam sine fenore alicui credere or expensum ferre: to refuse to pay either principal or interest, fenus (here = capital) atque impendium recusare (Liv.): to receive interest from anybody, usuram ab aliquo accipere: to pay interest, usuram pendere or solvere; to anybody, alicui fenus dare: to pay down the interest in hard money, pecuniam usuris pernumerare: to pay the capital without interest, pecunias creditas sine usuris solvere: the interest mounts up, usurae multiplicantur: the interest exceeds the capital, mergunt usurae sortem: the rate of interest falls, fenus deminuitur; rises, *fenus augetur: the profits of an estate are hardly sufficient to pay the interest with, fructus praediorum certant cum usuris: the interest is added to the capital, sors fit ex usurā: to add the interest to the capitat, usuram perscribere (☞ Brem., Suet., Caes., 42): a High, a moderately high, a shamefully high rate of interest, grande, tolerabile, iniquissimum fenas: to be ruined by the amount of interest one has to pay, fenore trucidari; impendiis debilitari (Cic., Rep., 2, 30).
