-ine

-ine is a suffix used in chemistry to denote two kinds of substance. The first is a chemically basic and alkaloidal substance. It was proposed by Joseph Louis Gay-Lussac in an editorial accompanying a paper by Friedrich Sertürner describing the isolation of the alkaloid "morphium", which was subsequently renamed to "morphine".^[1] Examples include quinine, morphine and guanidine.^[2] The second usage is to denote a hydrocarbon of the second degree of unsaturation. Examples include hexine and heptine.^[2] With simple hydrocarbons, this usage is identical to the IUPAC suffix -yne.

In common and literary adjectives (e.g. asinine, canine, feline, ursine), the suffix is usually pronounced

Some elements of the periodic table (namely the halogens, in the Group 17) have this suffix: fluorine (F), chlorine (Cl), bromine (Br), iodine (I) and astatine (At), ending which was continued in the artificially created tennessine (Ts).
