Pronunciation

  • /obliˈɡaɾ/, [o.β̞liˈɣ̞aɾ][1]

Forms

obligar (first-person singular present obligo, first-person singular preterite obligué, past participle obligado)[1]

Etymology

It is borrowed from Latin obligō (“to tie up; to bind by a contract or judgement; to force”), a learned word.[2][3][4][1] The Latin verb is made of ob- and ligō (“to bind, tie”).[5][1][6] Spanish continues the simple verb as ligar, a semi-learned form whose inherited outcome in the 13th century was legar.[2][3]

The same Latin verb gave Portuguese obrigar, Catalan obligar, Occitan obligar, French obliger and Italian obbligare.[7][8] The simple verb goes back to Proto-Italic *-lig-ā- and perhaps to Proto-Indo-European *liǵ- (“to tie”), with Albanian lidh (“to tie”) as a cognate; de Vaan notes that it is attested only from Catullus, later than its compounds.[9]

Earliest recorded meaning

The DCECH and the BDELC date it to a document of 1221 in Menéndez Pidal's Documentos lingüísticos, with another of 1247.[2][3] The DEMel lists an earlier me obligo in a document of 1162 from León and Castile.[10] The CDH's earliest hit in a Spanish text is the Fuero de Zorita de los Canes (1218–c. 1250), where a parish is answerable until all the money is paid por los quales fue obligada la collacion “for which the parish was bound”; its other early hits, of 1228–1236, are Latin charters with pignori obligare “to pledge”.[11] The first sense is thus legal: to bind oneself or others to pay or to fulfil something.[11][12]

Semantic evolution

In Alfonso X's legal prose the verb means “to commit oneself to fulfil something”.[12] The Diccionario de Autoridades defines it as to tie, bind, compel, move someone effectively to something even against his taste, and also as to win another's goodwill with favours or kindness, quoting a ballad: Persuadióla con halagos, / obligóla con cariños.[13] Terreros adds that laws oblige to their observance.[14] The Academy recorded the reflexive “to commit oneself, make oneself answerable” in 1817.[15] Baralt (1855) noted that in the sense “to win someone over with favours” the verb was used mostly in the past tenses.[16]

The 2001 Academy dictionary has the senses “to force a thing to obtain an effect” and, in law, “to subject property to the payment of debts”.[17] In Bolivia and Chile obligar meant to drink from the same glass as another person, and in Bolivia and (now obsolescent) in Argentina, to invite someone to drink the same amount, often from the same glass.[18][19]

Timeline

  • 1218–c. 1250 – the Fuero de Zorita de los Canes has obligada.[11]
  • 1221 – the first record in the DCECH and the BDELC.[2][3]
  • 1492 – Nebrija's Latin–Spanish dictionary uses it to gloss several Latin verbs, among them obiuro “to bind by oath”.[20]
  • 1525 – the first records from the Americas, in Mexico City: que yo… sea obligado de vos dar el título.[21]
  • 1726–1739 – the Diccionario de Autoridades gives the senses “to compel” and “to win over with favours”.[13]
  • 1817 – the Academy adds the reflexive obligarse “to commit oneself”.[15]
  • 1884 – the Academy gives the etymology Latin obligare and the definition “to move and impel to do or fulfil something”.[22]
  • 1946 – Malaret records the drinking custom of Bolivia and Chile.[18]
