Forms

basis f (genitive basis or baseōs or basios); third declension[1]

Etymology

It is borrowed from Ancient Greek βάσις (básis, “stepping, step, base”),[2][1][3] from βαίνω (baínō, “to go, step”), from Proto-Indo-European *gʷem- (“to go, come”).[4][1]

Earliest recorded meaning

It is found in Cicero (81–43 BC), who writes of a statue standing on a very high pedestal and of the base of trophies.[5][2][6]

Semantic evolution

It was the lowest part of a structure, a pedestal or foundation, as Cicero's base of a villa, and the base of a column in Vitruvius.[2][5] In geometry it was the base of a triangle, as Cicero's triangle formed by flying cranes, or the chord of an arc.[2]

Celsus used it in medicine for the base or attachment of an organ or tumour, and Vitruvius in astronomy for the lower part of a constellation.[2] Seneca's proverb “to measure someone with his pedestal” meant to overrate them.[5][7] English base came from it through Old French about 1300, and basis was borrowed in the 1570s.[4]
