spend: [OE] Spend is a blend of verbs from two distinct sources, but both going back ultimately to Latin pendere ‘weigh, pay’. The earlier was Latin expendere ‘pay out’ (later to give English expend [15]), which Old English took over as spendan. (It was also the source of German spenden.) This was later reinforced by dispend, a borrowing from Old French despendre which now survives only in dispense.

spend (v.)youdaoicibaDictYouDict
"to pay out or away" (money or wealth), Old English -spendan (in forspendan "use up"), from Medieval Latin spendere, a shortening of Latin expendere "to weigh out money, pay down" (see expend) or possibly of dispendere "to pay out." A general Germanic borrowing (Old High German spendon, German and Middle Dutch spenden, Old Norse spenna). In reference to labor, thoughts, time, etc., attested from c. 1300. Intransitive sense "exhaust, wear (oneself) out" is from 1590s (see spent).
