Etymology

It is inherited from Old Spanish mar, inherited from Latin mare (“sea”).[2][3][4][1]

The same word is Portuguese mar, Galician mar, Catalan mar, Occitan mar, French mer, Italian mare and Romanian mare.[1][5] The Latin noun was neuter;[2] it became feminine in Romanian and French and masculine in Italian and Sardinian, and the other Romance languages have had both genders.[2]

The Latin word goes back to Proto-Italic *mari- (“sea, lake”) and Proto-Indo-European *mor-i-, a word for any large body of water, with cognates in Old Irish muir, Lithuanian marės and Old High German mari “sea, lake”.[6] The Latin ⟨a⟩ comes from an unrounding of ⟨*mo-⟩ in an open syllable.[6]

Earliest recorded meaning

The Cantar de mio Cid (c. 1140, in a 14th-century copy) has the word in a prayer to God the creator: „Fezist cielo e tierra, el tercero el mar” “you made heaven and earth, and third the sea”.[7][3] The poem uses it as both masculine and feminine.[8]

Semantic evolution

Alfonso X's prose already has alta mar “the high sea” and mar Bermejo for the Red Sea.[9] Nebrija in the 1490s wrote mar honda and mar somera but mar Mediterráneo and mar Bermejo: the feminine for the sea in general and the masculine for named seas, the division still in use.[2]

Autoridades in 1734 recorded the use for large lakes (the Caspian, the Dead Sea) and for a great abundance, mares de lágrimas.[10] The 1884 dictionary records the swell of a stormy sea.[11] In colloquial speech la mar de means “very, a lot of”: es la mar de simpática.[4]

Timeline

  • c. 1140 – the Cantar de mio Cid uses the word in both genders.[3][8]
  • 1250–1279 – Alfonso X's Lapidario speaks of the great sea that surrounds the world.[9]
  • c. 1495 – Nebrija gives Latin mare and pontus as its equivalents.[12]
  • 1509 – first record in the Americas, in Puerto Rico.[13]
  • 1611 – Covarrubias records the saying ir de mar a mar for going with great force.[14]
  • 1734 – Autoridades describes the word as being of both genders.[10]
  • 1884 – the Academy's dictionary first gives its etymology, Latin mare.[11]

Usage notes

Mar is masculine in standard use (el mar, los mares) and in the names of seas, but feminine among sailors, in some regions and in many set phrases: alta mar, hacerse a la mar, pleamar, bajamar and la mar de “very”.[4][15][16] Both genders have been used since the Cid; sailors already preferred the feminine in the Golden Age, while Latin influence soon made the names of seas masculine.[2]
