inexact term for various metallic sulfates:

Происхождение

From Middle English coperas, coperose (“any metallic sulfate”), from Medieval Latin cupros

From Middle English coperas, coperose (“any metallic sulfate”), from Medieval Latin cuprosa directly or via Old French coperose, from Medieval Latin aqua cuprosa (“cupreous water”), from Latin cuprum (“copper”) + -osa (“-ose: forming related adjectives”). Fanciful derivations from cupreous terms involving Latin rosa (“rose”) are mistaken.
