debtor (n.)

early 13c., dettur, dettour, from Old French detour, from Latin debitor "a debter," from past participle stem of debere "to owe," originally, "keep something away from someone," from de- "away" (see de-) + habere "to have" (from PIE root *ghabh- "to give or receive"). The -b- was restored in later French, and in English c. 1560-c. 1660. The KJV has detter three times, debter three times, debtor twice and debtour once.
