cyanide=السيانيد
ONLINE ETYMOLOGY DICTIONARY
cyanide (n.)
a salt of hydrocyanic acid, 1826, coined from cyan-, comb. form for carbon and nitrogen compounds, from Greek kyanos "dark blue" (see cyan) + chemical ending -ide, on analogy of chloride. So called because it first had been obtained by heating the dye pigment powder known as Prussian blue (see Prussian).
cyan (n.)
1889, short for cyan blue (1879), from Greek kyanos "dark blue, dark blue enamel, lapis lazuli," probably a non-Indo-European word, but perhaps akin to, or from, Hittite *kuwanna(n)- "copper blue."
-ide
suffix used to form names of simple compounds of an element with another element or radical; originally abstracted from oxide, the first so classified.
