Pronunciation

Forms

debito m (plural debiti); adjective debito (feminine debita, masculine plural debiti, feminine plural debite)[1] Old Italian also had the popular forms Old Italian devito and Old Italian deveto, especially in Siena and Perugia.[2][3]

Etymology

It is borrowed from Latin dēbitum (“what is owed, debt”), the noun use of the neuter of dēbitus (“owed”), the past participle of dēbeō (“to owe”); the adjective is the participle itself.[4][5][6][1] DELI and GDLI call both learned, and the LEI notes that the adjective exists in Italo-Romance only in learned form.[4][7][8]

The Latin noun also lived on in popular forms: Romansh deivet, Old French det, Catalan deute and Sardinian déppidu, and in central Italy Old Sienese devito.[3][9] The plural dēbita gave Old Italian detta (“principal of a debt”), French dette, Spanish deuda and Portuguese dívida.[9][10] The learned word is also French débit and Spanish débito.[5][11]

Latin dēbeō is contracted from a compound of dē- (“away from”) and habeō (“to have, to hold”), “to hold something away from someone, to withhold”.[12]

The Italian phrase for the national debt is a calque of French dette publique, and the one for a floating debt renders dette flottante.[4][11]

Earliest recorded meaning

The TLIO's first record is a document from Montieri of 1219, for what is owed materially or morally.[2] DELI dates the adjective “due, required by obligation or circumstance” to Guittone d'Arezzo (before 1294), with a Venetian record of 1282, and the noun “money owed” to a Volterra document of before 1322.[4]

Semantic evolution

The sense “moral duty” is in Giordano da Pisa (1303–1306), and Dante uses the noun for a moral obligation.[4][11] The religious debiti are the sins for which man owes God, as in the Lord's Prayer: rimetti a noi i nostri debiti, “forgive us our debts”.[6] Old Italian rendere or rimettere il debito meant to forgive a wrong received.[2] Debitore “debtor” is older than the noun, in Mazzeo di Ricco early in the 13th century.[4]

The word passed into the German of merchants as Debit (1552).[13] Modern uses include the economist's debito pubblico and debito estero, the physiologist's debito d'ossigeno, and in the upper secondary school a deficit in a subject that the pupil must make up.[6][14][15]
