Forms

diabo m (plural diabos)[1] The oldest texts write diabo, diaboo and diabre, and the Crónica Geral also has diabro in one manuscript.[2][3][4] According to the DDGM, diaboo is found from the 13th to the 15th century.[4]

Etymology

It is inherited from Late Latin diabolus (“devil”), the word of the Church, which is from Ancient Greek διάβολος (diábolos, “slanderer; one who sets apart”).[2][5][1] Wiktionary considers it a semi-learned word, and the oldest texts have Old Galician-Portuguese diaboo beside Old Galician-Portuguese diabre and Old Galician-Portuguese diabro; that form won out over the others.[1][2]

The same Latin word is Spanish diablo, Catalan diable, French diable, Italian diavolo and Romanian diavol.[6] Galician has diaño.[1] In Spanish the word is first recorded as diábolo around 950 in the Glosas Emilianenses.[7]

The Greek noun is formed from διαβάλλω (diabállō, “to slander”), a compound of δια- (dia-, “through”) and βάλλω (bállō, “to throw”).[1][7] In classical Greek the word was an adjective, “that sets people against each other”, and as a noun it meant “slanderer”;[8] Christian Greek used it for the Devil.[8]

Nascentes explains the modern form by the loss of the intervocalic /l/ and the merging of the two /o/ vowels of the older form.[5] In his fuller dictionary he notes that the /b/ kept between vowels is due to learned influence or to the confusion of /b/ and /v/.[9] Because it was a taboo word, it gave rise to many euphemisms, such as diacho, dianho and dialho.[2]

Earliest recorded meaning

The word is recorded from the 13th century.[2] The Cantigas de Santa Maria speak of “the deceit of the devil” (por engano do diabo) and of devils “much blacker than coal”, and use the forms diaboo and diabre as well.[3][10] Already in these texts the word names the Devil and the demons in the plural.[3]

Semantic evolution

In the medieval texts the word is the Christian Devil and his demons.[3] Morais (1789) also records it of a very clever, lively man.[11] Figueiredo (1899) adds the figurative senses of a bad-tempered or ugly person, and a variety of pear.[12] Modern dictionaries add a mischievous child, an intensifier (a festa foi o diabo “it was a mess”), an expletive after a question word (que diabo…?) and an interjection of anger or surprise.[2][13] In Brazil the word also renders the Tupi spirit Jurupari, and in the textile mills it named a machine for opening wool.[2][14]
