azo-comb. form

Stress is determined by a range of factors though some degree of stress is usually maintained on this combining form.

Origin: Formed within English, by clipping or shortening. Etymon: azoto- comb. form.

Etymology: Shortened < azoto- comb. form.Compare French azo-, German azo-.In azohumic adj. at sense 1 after French azhumique (1870 or earlier).In azolitmin n. at sense 1 < German Azolitmin (1841) < azo- azo- comb. form + Litmus litmus n. + -in -in suffix¹.In azoleic acid n. at sense 1 after French acide azoléique (1837 or earlier).

Chemistry.

Short combining form of azote n., nitrogen. Used to form the names of:

1. gen. Compounds containing nitrogen, as azoˈhumic adj. nitrogenized humic (acid). azoˈlitmin n. the principal colouring matter of litmus. azoˈleic acid n. an acid formed by treating oleic with nitric acid.

2. spec. Substitution compounds in which nitrogen takes the place of another element, as in the azoˈparaffins n. formed from the paraffins by substitution of 1 atom of nitrogen for 3 of hydrogen: e.g. azo-methane = hydrogen cyanide, azo-ethane = methyl cyanide, azo-propane = ethyl cyanide, etc.

a. more particularly. Compounds derived from the aromatic hydrocarbons, which contain nitrogen combined in a peculiar way, constituting the azo- and diazo- compounds, or azo- derivatives, e.g. azobenzene, azotoluene; diazo-amidobenzene, diazo-bromide; whence adjectives as azobenˈzoic, etc.
