Pronunciation

  • Brazil: /ˈse.bu/[1]
  • Portugal: /ˈse.bu/, [ˈse.βu][1]
  • Portugal, Southern: /ˈse.bu/[1]

Forms

sebo m (plural sebos)[1] Old Galician-Portuguese wrote sevo, and the 15th century seuo;[2][3] sebo and cebo appear about 1720.[2][3] Bluteau (1712–1728) enters the word under cebo.[4]

Etymology

It is inherited from Latin sēbum (“tallow, suet”), written Old Galician-Portuguese sevo in the oldest texts.[2][3][5][1] Latin also had the spelling sēvum, and Porto Editora gives both as the source.[6][7]

The same Latin word is Galician sebo, Spanish sebo, Catalan sèu, French suif and Italian sego.[1][8] Old Spanish had sevo too, from the middle of the 13th century.[9] The French word adds an /f/ by analogy, from older seu.[10]

Wiktionary derives the Latin word from Proto-Indo-European *seyb- (“to pour out”), the root it also gives for Germanic *saipǭ (“soap”).[1] De Vaan is doubtful: a /b/ is very rare in Proto-Indo-European roots and the meaning of the Latin word need not have anything to do with dripping, so he leaves it without an etymology.[11]

Earliest recorded meaning

Houaiss and Cunha date sevo to the 13th century.[2][3] In the Cantigas de Santa Maria a pilgrim brings candles de çera, ca non de sevo “of wax, not of tallow”.[12]

Semantic evolution

The word first meant animal fat used for candles, soap and grease, as in the cantiga above;[12][13] Morais (1813) still defines it as the fat of oxen and sheep used for candles and soap.[12][13] From there it came to mean any greasy layer, the grime on a collar, and in medicine the secretion of the skin's glands.[2][14]

In Brazil sebo is also a shop that buys and sells second-hand books, and now records and magazines as well.[2][14][1] Wiktionary dates this sense to the middle of the 20th century and calls its origin unknown, suggesting a transfer from the tallow candles of such shops or from the grime that covers old books, a development like that of sebenta “lecture notes”.[1] In Pernambuco the shop is also called caga-sebo, a name otherwise given to several small birds.[15][16][17]

Other Brazilian senses are “courtship” and “a conceited, tiresome person”, and the word is used as an interjection of annoyance, sebo! or ora sebo!.[2][14] Silva Bastos already recorded the interjection in 1912.[18]
