Pronunciation

  • IPA (Classical): [ˈdeː.be.oː][1]
  • IPA (Ecclesiastical): [ˈdɛː.be.o][1]

Forms

dēbeō (present infinitive dēbēre, perfect active dēbuī, supine dēbitum); second conjugation[1] Plautus has the uncontracted perfect dēhibuistī.[2][3]

Etymology

It is from Latin dē- (“away”) + habeō (“to have”) by contraction, literally “to hold back from someone, withhold”.[2][3][4]

Earliest recorded meaning

Plautus uses it of owing money.[2][3] Köbler dates Plautus c. 250–184 BC.[5]

Semantic evolution

Cicero explains the old sense: the debtor keeps someone else's money.[6] In Classical Latin it was to owe money, to be legally bound to give, to owe services, thanks or one's life, and, with an infinitive, “ought, should”, for moral, logical or practical reasons.[3] Fate could “owe” a death, and the passive meant “to be due”.[3][1]

In medieval Latin it kept the senses “must, owe, be bound”.[7] It survives as Italian dovere, French devoir, Spanish deber and Portuguese dever.[1]

Timeline

  • c. 250–184 BC – Plautus uses it of owing money.[3][5]
  • c. 1300 – English debt is recorded, from dēbitum “thing owed”.[8]
  • late 14th century – English due is recorded as “owed, payable”, from Old French deu, from dēbēre.[8]
