Etymology

It is inherited from Latin testū (“an earthenware lid; clay pot”), also testum.[2][3][1][4] Houaiss notes that the Latin word lives on in all the Romance languages.[2] Adolfo Coelho and Bluteau derived it instead from testa (“a piece of burnt clay”), the source of the Latin noun itself.[5][6]

The same Latin word is Galician testo, Spanish tiesto, Catalan test, Italian testo, Old French test and Romanian țest.[7][1] The Spanish word is recorded from 1220–1250.[8]

Wiktionary too derives the Latin noun from that word.[1][1]

Earliest recorded meaning

The oldest records have the sense “skull, the top of the head”: the Crónica de 1344 tells of a blow that cut through helmet and mail e o testo da cabeça, and the Crónica Troiana of sword blows that went through the helmet ata o testo “down to the skull”.[9] The DDGM calls this a medieval sense.[9]

Semantic evolution

The sense “pot lid” is the one the dictionaries record from the 18th century: Bluteau describes a round piece of baked clay with a knob in the middle, used to cover pots and pitchers.[6] Morais (1789) adds an earthen pot holding lime for whitewashing, and testo do boi “the skull of an ox”.[10] Aulete records the Minho phrase servir de testo “to act as a go-between”.[11] The DLP lists further popular and regional senses: “hat”, a tostão coin, sponge cake, and in the Azores a shard of crockery and a woman of bad reputation.[4] In Brazil it is also the crust of soot on the bottom of pots.[2][4]

Timeline

  • 14th century – first records, in the sense “skull”.[2][9]
  • 1344 – the Crónica de 1344 has o testo da cabeça.[9]
  • 1712–1728 – Bluteau defines the pot lid.[6]
  • 1734 – Feijó distinguishes testo with close /e/ “lid” from tésto with open /ɛ/ “resolute”.[12]
  • 1789 – Morais records the lime pot and the ox's skull.[10]

Meanings

Noun

  1. A lid of clay or iron for a pot or pan: tira o testo à panela.[2][4][1]
  2. An earthen pot in which lime is kept for whitewashing.[2][4]
  3. The skull of an ox.[2][4]
  4. (Brazil) The layer of soot stuck to the bottom of pans.[2][4]
  5. (informal) The head; the brains.[2][11]
  6. (in the plural) The horizontal sides of a frame saw.[2][4]
  7. (Portugal, informal) Sponge cake (pão-de-ló).[2][4]

Usage notes

In Ceará testo with open /ɛ/ means “a punch”: Houaiss takes it from this noun with a change of the stressed vowel, and Nascentes explains it as a blow on the top of the skull.[2][3][13]

The adjective testo with open /ɛ/ “firm, resolute; serious” is a separate word, from testa, recorded from the 15th century.[2][14][4]

Informal Portuguese also has testo as a clipping of testosterona “testosterone”.[1]
