Forms

lagarto m (plural lagartos)[1]

Etymology

It is inherited from Vulgar Latin *lacartus, a by-form of Latin lacertus (“lizard; upper arm, muscle”).[2][3][4][1] The oldest texts have Old Galician-Portuguese lagarto.[5] Houaiss notes that the word kept both Latin senses, the reptile and the muscle of the arm.[2] Nascentes explains that only the assimilated form with ⟨a⟩ accounts for the /ɡ/: before ⟨e⟩ the Latin /k/ would have become /z/.[6] Corominas takes this form for an old dialectal variant of the Latin word.[7][8]

The same form is Spanish lagarto, Galician lagarto and Asturian llagartu, while French lézard and Italian lucertola continue the Latin forms with ⟨e⟩.[9][1][10] Spanish has the word as a name in documents of 1095 and 1171 and as a common noun from the 13th century.[7]

The origin of the Latin word is obscure: de Vaan finds none of the proposed connections, with Greek words for the foot and kicking and with leggr (“leg”), convincing.[11] Wiktionary leaves open whether the lizard was named from the muscle or the muscle from the lizard.[1]

Earliest recorded meaning

Houaiss dates the first record to the 15th century, from Cunha's index of medieval Portuguese;[2][3] Cunha's own dictionary has the 16th century.[2][3] The diminutive lagartixa is already in a document of 1359 cited by the Elucidário.[12]

Semantic evolution

The muscle sense is old: Morais (1789) has lagarto do braço for the flesh between the elbow and the shoulder and lagarto da perna for the calf, and Bluteau quotes a surgeon who made lagarto the same as lacerto “muscle”.[13][14] Nascentes compares the Brazilian name of a cut of beef to the twitching of the muscle under the skin, like a lizard running past.[15]

The writers of the discoveries called the crocodiles of Africa and southern Asia lagartos or lagartos de água;[16] Dalgado quotes Duarte Barbosa in 1516 on the great lagartos of Cannanore that eat men.[16] Bluteau and Morais still give “crocodile” as a sense, and Houaiss keeps the Nile crocodile for Guinea-Bissau.[14][13][2] In Brazil the word names the large teiid lizards, the teiú.[4][2] In Portugal it is also a fish of the Azores and, after the club's green colour, a derogatory name for supporters of Sporting.[17]

The word passed into Guinea-Bissau Creole as lagártu.[1]
