sexta f (genitive sextae); first declension[1]

Etymology

It is from Latin sextus (“sixth”), its feminine used as a noun in agreement with an implied hōra (“hour”), “the sixth hour”.[1][2] Köbler likewise derives it from the ordinal.[3]

Earliest recorded meaning

Köbler's earliest source for the noun is the Peregrinatio Aetheriae;[3] it named the sixth hour of daylight, noon, and the office said at that hour.[1][3]

Semantic evolution

In Classical Latin the feminine sexta was used, by itself or with pars, for one-sixth of something.[4]

The sixth hour of daylight was noon,[1] and in the Church sexta became the name of the office said at that hour, Sext, one of the canonical hours.[5][6][2] Gregory of Tours records that a bishop of Tours had Terce and Sext said in his church.[7]

Medieval music theory used it for the sixth degree of the scale and for the interval of a sixth.[8] Du Cange also lists it as a measure of liquids and as the name of a forbidden game in the statutes of Pistoia.[7] It is the source of Spanish siesta and Portuguese sesta.[1]
