Forms
sujo (feminine suja, masculine plural sujos, feminine plural sujas, comparable, comparative mais sujo, superlative o mais sujo or sujíssimo, diminutive sujinho)[1] Old Portuguese wrote çujo, çuyo and suzio in the 14th century, and suja, çuio and suzia in the 15th.[2][3] Galician texts of the same time have suzio and suçio.[4]
Etymology
It is inherited from Latin sūcidus (“juicy, moist; greasy (of unwashed wool)”), also spelt succidus, and is written Old Galician-Portuguese çujo in the oldest texts.[2][3][1][5][6] Nascentes and Aurélio trace it through the intermediate forms *sucio and *susiu.[7][8] Meyer-Lübke already posited a Latin sense “dirty” for the word.[9] Morais (1813) and Michaelis take it instead from the Spanish word.[10][11]
The Latin adjective is formed from sūcus (“juice, sap”) with the suffix -idus.[1][12] It was used chiefly of freshly shorn wool, still damp with sweat and grease, which is how it came to mean “dirty” in Romance.[13][14][12]
The same word is Galician suxo, Spanish sucio and Old Occitan sotz.[1][9][15]
Earliest recorded meaning
The chronicle of 1344 has seus çujos custumes e da çuja ley “their dirty customs and their dirty law” and o logar era çujo assaz “the place was very dirty”; the Galician Miragres de Santiago speak of evil spirits that are maaos et suçios.[4] Houaiss and Cunha date the word to the 14th century.[2][3]
Semantic evolution
Beside the physical sense, the word was used early of morals: Bluteau (1712–1728) has it for “dishonest, unchaste” and for foul words.[16] Morais (1813) adds a sea sujo full of islets and reefs, and a book sujo full of misprints.[10] Modern dictionaries add dishonest dealing, a bad name, an indecent mouth, a hazy horizon and an infected place.[8][17][11]
In Brazil, as a noun, o sujo or porco sujo is a popular name for the devil, and sujos are carnival revellers dressed in rags.[17] Regional surveys record a seabed with stones in Portugal, and in Pará the soot of a kitchen.[18] The Saramaccan word súndju comes from it.[1]
