Pronunciation

  • Brazil: /ˈba.zi/[1]
  • Portugal: /ˈba.zɨ/[1]

Forms

base f (plural bases)[1] The 14th century has basa, and the 16th the learned Latin form basis.[2][3][4]

Etymology

It is borrowed from Latin basis (“base, pedestal”), a learned word, which is from Ancient Greek βάσις (básis, “a stepping; step, foot; base, pedestal”).[2][3][4][1] Nascentes and Aurélio give the Greek sense as “sole of the foot”.[5][6] The Latin word was itself taken from Greek.[7][1] The Greek noun belongs to the family of βαίνω (baínō, “to walk”), from a root that the DHLF gives as Proto-Indo-European *gʷem-.[8]

The same Latin word is French base and Spanish base;[8][9] Spanish also has basa.[8][9] Houaiss notes that the Greco-Latin sense passed into the language of architecture, sculpture, mathematics, music and botany, and that the French chemist Guillaume François Rouelle was the first to use it in chemistry.[2]

Earliest recorded meaning

The earliest record is basa in the 14th century, in Cunha's index of medieval Portuguese.[2][3] The learned basis appears in the 16th century, in a passage on the houses of the Zodiac in the Eufrosina, and the form base in 1601, in B. Teixeira's Prosopopeia, figuratively: Estriba, como em base só fortíssimo “it rests, as on a single very strong base”.[4][3]

Semantic evolution

Houaiss dates the architectural sense, the lower part of a column on which the shaft rests, to 1572.[2] Bluteau (1712–1728) defines it so, adds the base of a statue and of a triangle, and records a pharmaceutical sense, the main ingredient of a medicine.[10] Morais (1789) adds the chemical sense, the body that a solvent combines with.[11] Vieira (1871–1874) describes the general sense, whatever supports a body above it, and the figurative one, a fundamental principle.[12]

Modern dictionaries add a first coat of paint or make-up (base para maquilagem), the road-building sense (dated by Houaiss to 1952), and many technical senses in electronics, linguistics and mathematics.[2][13] The Portuguese Wiktionary also gives the sense “headquarters”.[14]
