Pronunciation

  • IPA: /sɪksθ/[1]

Etymology

It is Middle English sixte, inherited from Old English siexta, syxte, from siex (“six”),[2][3] with the ending later changed to match -th.[2][3] Old Frisian sexta, Old High German sehsto and Gothic saihsta are related.[2][3] See six.[2]

Earliest recorded meaning

The ordinal of six: before 900 in the OED.[4] The Middle English form sixte is from about 1200, and the form in -th from the late 14th century; it replaced sixte by the 16th century.[2]

Semantic evolution

After the names of kings and popes, as in Henry the Sixth, it is from 1387.[4] The noun, a sixth part, is from 1557,[4][2] and in music, an interval of six degrees, from 1597.[4][2] Sixth form, the top classes of a British secondary school, follows the elliptical use from 1573.[4] The sixth sense, a supposed faculty of perception beyond the five senses, is from 1712; earlier, in the 1690s, it was the sense of sexual pleasure, after Scaliger.[2]
