Pronunciation

  • IPA: /ˈtɒk.sɪk/ (UK)[1]

Etymology

It is borrowed from French toxique and directly borrowed from Late Latin toxicus (“poisoned”),[2][3][4] from Latin toxicum (“poison”), from Ancient Greek τοξικόν (toxikón), in toxikòn phármakon, poison for arrows,[2][3][5][6] the neuter of τοξικός (toxikós, “of a bow or archery”), from τόξον (tóxon, “bow”).[2][3] The Greek word has been taken as a Scythian loanword, from Iranian taxša-, bow (Watkins), or as Pre-Greek (Beekes).[3][2]

Earliest recorded meaning

Poisonous: 1664, in John Evelyn's Sylva.[2][7][3]

Semantic evolution

Caused by poison, as toxic symptoms, is from 1872;[7] toxic shock syndrome follows.[7] As a noun, a toxic substance, it is from 1890.[7][3][8] Word Origins notes that intoxicate comes from the related toxicum and has been associated with alcohol since the late 16th century.[6] Figurative uses for anything very harmful, such as a toxic relationship, and in finance for an asset likely to cause great loss, are recent.[9]
