Forms

morder (first-person singular present mordo, first-person singular preterite mordi, past participle mordido)[1]

Etymology

It is inherited from Latin mordeō (“to bite”), written Old Galician-Portuguese morder in the oldest texts.[2][3][1][4]

The same Latin verb is Galician morder, Spanish morder, Catalan morder, French mordre and Italian mordere.[5][1]

De Vaan reconstructs Proto-Italic *mordeje- and a present Proto-Indo-European *h₂mord-(e)ie- (“to crush, bite”).[6] Wiktionary derives it from the root *(s)merd- (“to bite, sting”) and compares Sanskrit मर्दति (márdati, “presses, crushes”), Ancient Greek σμερδνός (smerdnós, “dreadful”) and the English word smart.[1]

Earliest recorded meaning

The Cantigas de Santa Maria speak of sheep “eaten or badly bitten by wolves” (de lobos log' enton / comestas ou mal mordudas), with the old participle mordudo, and of sick people who “began to bite like a fierce dog” (que sse fillavan a morder / come can bravo).[7] The Crónica Troiana already uses it figuratively, of deeds that come “to bite and gnaw” at the good.[7]

Semantic evolution

Houaiss dates the figurative sense “to torment, trouble” to the 15th century, when the forms mordeo and murde are also recorded.[2] Bluteau's dictionary of 1712–1728 uses the verb for sharp humours that sting the body and for scruples that gnaw at the conscience.[8] Morais in 1789 adds the poetic morder a terra “to fall dead in battle” and the sense “to criticize, satirize”.[9]

Modern Portuguese uses it for anything that grips, wears or etches like teeth: gears, rust, acids in engraving.[2][10] Brazilian informal speech uses it for cadging money from friends and relations, and Portuguese slang for “to steal” and “to understand”.[2][11][12][4] On the Internet it has come to mean “to take the bait”.[1]

Timeline

  • 13th century – the Cantigas de Santa Maria have morder and the participle mordudas.[7]
  • 1344 – the Crónica Geral has mordeu ẽna maçãa “bit into the apple”.[7]
  • 14th century – the form morde is recorded.[2]
  • 15th century – first record of the figurative sense “to torment”.[2]
  • c. 1450 – the Livro das tres vertudes uses the verb.[13]
  • 1569 – Cardoso glosses it with the Latin mordeo.[14]
  • 1712–1728 – Bluteau records the senses of stinging humours and of scruples.[8]
