Forms

desligar (first-person singular present desligo, first-person singular preterite desliguei, past participle desligado)[1] The 14th-century form is deslegar, after the old form legar of ligar.[2][3] Cunha also records desliar.[2][3]

Etymology

It is formed from Portuguese des- + ligar, first written Old Galician-Portuguese deslegar.[2][3][4][1] The base verb, old Old Galician-Portuguese legar, is from Latin ligō (“to bind, tie”).[5][3] Wiktionary traces the Latin verb to *leyǵ- (“to bind”), and treats desliar as a doublet, from the popular form liar.[1][6]

Earliest recorded meaning

Houaiss's first record, from Cunha's index of medieval Portuguese, is of the 14th century, with the old form deslegar.[2] Bluteau's quotations show the sense “to unbind, loosen”: Os que desligaõ de si as cadeas das falsas alegrias “those who unbind from themselves the chains of false joys”.[7][8]

Semantic evolution

Bluteau sends the reader to desatar “to untie”, and Morais (1789) gives “to untie”, “to unfasten” and “to dissolve a union”.[7][8] The figurative “to release from an obligation” and the theological “to absolve” (the Church's power to bind and loose, ligar e desligar) are recorded in the old Caldas Aulete.[9][10] The verb has taken the technical sense “to switch off, disconnect” (an appliance, a motor, the gas) and “to hang up” (a telephone), now its commonest use.[2][4][1] It also means “to dismiss from a post”, and informally in Portugal “to stop paying attention”.[2][11][4]

Timeline

  • 14th century – first record, as deslegar.[2][3]
  • 1712–1728 – Bluteau enters desligar with quotations.[7]
  • 1789 – Morais defines it as “to untie the bindings”.[8]
  • 1844 – first record of desligamento.[3]
