Pronunciation

  • UK: /ˈkwɒl.ɪ.tə.tɪv/[1]
  • US: /ˈkwɑ.ləˌteɪ.tɪv/[1]

Etymology

It is borrowed from Late Latin quālitātīvus (“concerned with quality”),[2][3][4][5][6] which the OED records from the 6th century and frequently from the 12th in British sources;[2] Etymonline, Klein, the AHD and the MED call it Medieval Latin.[2][7][8][9][10] It is formed from quālitās (“quality”) and -īvus.[2][3] Etymonline notes that quālitās is said to have been coined by Cicero to translate Ancient Greek ποιότης (poiótēs), and derives it from quālis (“of what kind”), from Proto-Indo-European *kwo-.[7] The first, medical use was qualitatif;[10][7] Etymonline thinks the later sense came from French qualitatif or the Latin word.[7] The OED compares Spanish cualitativo (1493) and Italian qualitativo (1353), and notes that quantitative is older in English.[2]

Earliest recorded meaning

Of medicines, supplying one of the four primary qualities: probably before 1425, in a Middle English translation of Guy de Chauliac.[10][7] The OED's first record is from 1607, in a sermon by Samuel Collins.[2]

Semantic evolution

The Middle English word belonged to medieval medicine, where drugs were classed by the qualities (hot, cold, moist, dry) they supplied.[10] The modern sense, "of or relating to quality", dates from about 1600,[7][2][3] and in later use the word was often paired against quantitative.[2][3][11] In chemistry qualitative analysis identifies which constituents a substance contains, as against how much of each.[5] Grammars from 1872 speak of a qualitative adjective, one that names a quality and can be compared.[2] In West African English it has meant "of high quality, excellent" since the 1970s.[2]
