-uret Chem.,|jʊərɛt|
a suffix, ad. mod.L. -urētum, -orētum, added to a stem or truncated word to form names of simple compounds of an element with another element or a radical. First used (after F. words in -ure) about 1790 in azoturet, hydruret, phosphuret, sulphuret (from azote, hydr-ogen, phosph-ure, sulph-ure), it was extended to other terms, as carburet, nitruret (1794), ioduret (1816), seleniuret (1818), and (more recently) arseniuret, bromuret, chloruret, cyanuret, floruret, hydroguret, telluret, etc. It is now largely replaced by -ide, q.v.
The French school of chemists in 1787 proposed the suffix -urētum, -orētum, in mod.L. terms (as phosphorētum, sulphurētum); but in F. words they preferred the suffix -ure (1787 De Morveau, etc. Méthode de Nomenclature Chimique 207, 231, etc.). |
