-insuffix1

Primary stress is retained by the usual stressed syllable of the preceding element and vowels may be reduced accordingly.
Origin: A variant or alteration of another lexical item. Etymon: -ine suffix5.
Etymology: Variant of -ine suffix5, originally after formations in the equivalent German suffix -in (as e.g., in the late 18th cent., olivin , variant of olivine n.).In the early 19th cent. spellings of words formed in -ine suffix5 often vary between -ine and -in more or less indiscriminately (compare forms at albumin n., aniline n., benzine n., gelatin n., glycerine n., saponin n.). Words formed within English that are spelt with -in in their earliest use include e.g. haematin n., lignin n., ulmin n. A formal distinction between the two spellings in chemical nomenclature (as explained at the definition) was proposed by A. W. von Hofmann, director of the Royal College of Chemistry (a1860), used systematically in Watts's Dict. Chem. (1866), and subsequently adopted by the (London) Chemical Society.

Also forming the names of certain non-nitrogenous heterocyclic compounds with six-membered rings, as dioxin.In some cases, forms spelt with -ine had passed into popular use before the formalization of the nomenclature, such as dextrine, gelatine, glycerine, which are still commonly so spelt in non-scientific use. For the naming of enzymes, -in (as in pepsin, trypsin) has been displaced by -ase (see -ase suffix).See also -ein suffix, -mycin suffix, -trophin comb. form, -tropin comb. form.
