úcarë

debt, trespass

#úcarë noun "debt, trespass" (úcaremmar "our debts, our trespasses", VT43:19). The related words #úcar- "to sin" and #úcarindo "sinner" would suggest that #úcarë can also be translated "sin". One may question whether the simplex form is #úcarë or just #úcar (+ -e- as a mere connecting vowel before the pronominal ending in úcaremmar), but compare lacarë, hrúcarë.
