Etymology

It is inherited from Old Spanish martes, inherited from Latin Mārtis diēs (“day of Mars”), the day being consecrated to the god.[2][3][4][1] Spanish kept only the genitive of Mārs, the Roman god of war, with its final -s.[2][5] Gómez de Silva describes the Roman name as a translation of the Greek name of the day, “day of Ares”.[5]

The same Latin phrase gave Italian martedì, French mardi, Romanian marți and Sardinian martis.[6][7] The -s of lunes is not Latin: Corominas explains it from the endings of this word, jueves and viernes.[8]

Wiktionary derives the god's name from the older form Māvors; its further origin is uncertain, and de Vaan discusses the Oscan and Umbrian names of the god.[1][9]

Earliest recorded meaning

Corominas dates the word from a document of 1219, and the DEMel has it in the Anales toledanos of the same year.[2][10] The Fuero de Zorita de los Canes (1218–c. 1250) gives water to the gardens dos dias en la semana, el martes et el miercoles, “two days a week, Tuesday and Wednesday”.[11] The fueros of Cáceres and Usagre still mix the word with Latin, in die dominico, et die martes, in a rule on the days women may use the baths.[11]

Semantic evolution

Nebrija gave Latin dies martis and feria tertia “the third weekday”.[12] The Diccionario de Autoridades called it the third day of the week, named after the planet Mars, and quoted Mariana and Quevedo on Tuesday as an unlucky day.[13] In 1899 the Academy recorded the proverb en martes, ni te cases ni te embarques, “on a Tuesday neither marry nor set sail”.[14][15] In 2001 the Academy's dictionary called it the second day of the week and the third of the liturgical week; the DLE now calls it simply the second day.[16][4]

The belief in an unlucky Tuesday was shared by the Sephardim of the Balkans, whose Judeo-Spanish proverbs warn against marrying or starting anything on that day.[17] The word passed into Tagalog Martes and into other languages of the Philippines.[1]

Timeline

  • 1219 – the first record, in the Anales toledanos.[10][2]
  • 1218–c. 1250 – the Fuero de Zorita de los Canes sets water turns for Tuesday and Wednesday.[11]
  • 1250–1279 – Alfonso X's Lapidario links the day with the planet Mars.[18]
  • c. 1495 – Nebrija glosses it dies martis, feria tertia.[12]
  • 1541 – the first record from the Americas, in Mexico City, for the days on which tributes were sold.[19]
  • 1817 – the Academy's dictionary records the phrase dar con la del martes.[20]
  • 1899 – the Academy gives the etymology Martis dies and the proverb on Tuesday as an unlucky day.[14]

Meanings

Noun

  1. Tuesday, the second day of the week, after lunes and before miércoles: Nos vemos el martes en la oficina.[4][1]
  2. martes de carnaval: Shrove Tuesday, the last day of carnival, before Ash Wednesday.[21]

Usage notes

The plural is the same as the singular: los martes.[1] In the 19th century dar con la del martes meant “to taunt someone with a defect”; in the 17th century it meant “to deceive”, and today the DLE defines it as “to do someone physical or moral harm”.[20][2][4] Moliner notes that Tuesday counts as unluckier still when it falls on the 13th.[15]
