/ˌtɔdəˈmɛrɪk/,

/ˌtɑdəˈmɛrɪk/

Origin: Formed within English, by compounding; perhaps modelled on a French lexical item, or perhaps modelled on a German lexical item. Etymons: tauto- comb. form, -meric comb. form.

Etymology: < tauto- comb. form + -meric comb. form, after French tautomérique (1886 or earlier) or its model German tautomer (C. Laar 1885, in Berichte der Deutsch. Chem. Ges. 18 654). Compare French tautomère (1886 or earlier). Compare tautomerism n.
