Forms
assassino (feminine assassina, masculine plural assassinos, feminine plural assassinas)[1]
Etymology
It is borrowed from Italian assassino (“murderer”), from Arabic حَشَّاشِين (ḥaššāšīn, “hashish users”).[2][3][4][5] Houaiss, Cunha, Machado and Nascentes all take the word through Italian, where it is old.[2][3][4][5] Houaiss notes that some see the influence of French assassin as well, and Aurélio names both the French and the Italian word as the route.[2][6] Wiktionary gives the Arabic plural or, as an alternative, أَسَاسِيُّون (ʔasāsiyyūn, “fundamentalists”).[1]
The Arabic name was given to the members of an Ismaili sect of the time of the Crusades, who were said to take hashish before killing the Christian or Sunni leaders their chief named.[2][4][5] Corriente traces the Ibero-Romance words to a Neo-Arabic form with the same meaning, applied in the Middle Ages to the Ismaili terrorists.[7] In Italian the word is recorded as assessino before 1290 and in its present form at the end of the 13th century for a follower of the sect.[8][2] Dante uses it for a murderer before 1321.[8][2]
The same word is Spanish asesino and Catalan assassí, and the French word as well.[7][9] French has it in the sense “hired killer” from 1560, borrowed from Italian.[7][9]
Earliest recorded meaning
Houaiss and Cunha date the word to the 15th century, in the spellings assassino and asasino.[2][3] An old text that Machado quotes still uses it as the name of the sect: men made bold and fearless by a draught, “who are called asasinos by the people”.[4]
Semantic evolution
In the 16th century Frei Diogo do Rosário's Summa Caietana explains that assassinos were infidels who went about killing Christians on command, and that jurists and common speech call so those who kill someone for money or at another's request.[4] Morais (1813) defines the noun as one who gives a violent death, and records the spelling Assacino in a law.[10] Figueiredo (1899) has the noun “one who kills treacherously or with premeditation” and the adjective “that murders”.[11]
The original Caldas Aulete adds the figurative sense “destroyer, one who causes ruin”.[12] The modern dictionaries also use the adjective of things that kill or that inspire a deadly passion.[2][13][14] Cunha dates assassinar and assassinato to the 17th century and assassínio to the 18th.[3]
