Pronunciation

Forms

dator m or n (feminine singular datoare, masculine plural datori, feminine/neuter plural datoare)[1] Old forms are deatoriu, deator, detor, dător, datur and adetor, and a regional one is ditor.[2][3]

Etymology

It is inherited from Vulgar Latin *dēbitōrius, a form standing for Latin dēbitor (“debtor”).[2][4][3][5][6][1] The Latin noun is formed on dēbeō (“to owe”), which DELR takes from dē- and habeō (“to have”).[2] The regular outcome was detor: DELR explains the vowel of dator by confusion with an old homonym meaning “giver”, formed on da “to give”, and Ciorănescu and DEX 2009 likewise see the influence of that verb.[2][4][5]

It survives in Aromanian as dãtor.[4][7][1] The Romance cognates include Occitan deudor, Spanish deudor and Portuguese devedor.[4][8] Ciorănescu notes that Albanian dëtürë (“debt”) could come from Romanian.[4]

Earliest recorded meaning

DELR's first record is deatoriu in the Codex Bratul of 1559–1560, meaning “owing”.[2] Tiktin cites the Psaltirea Scheiană (Psalm 108:11), and MDA2's first record is Coresi's homily book of 1581.[6][3]

Semantic evolution

The word first meant owing money, then owing anything: being bound, by law, agreement or conscience, to do something, and being indebted to someone for a kindness, hence grateful.[2][5][3] The old language also used it as a noun, “debtor”: a psalter of 1680 has cum și noi iertăm datorilor noștri “as we forgive our debtors”.[6] MDA2 also records the noun in the old sense “debt” and regionally as “debtor”.[3]

The family is older than the adjective in the record: datorie “debt; duty” is found in 1527–1538 and datornic “debtor” in 1551–1553.[2] The verb datora appears around 1800 with Micu, and datorită “thanks to”, the feminine participle of datori, with Eminescu in 1878.[2]
