Word Origin & History

amalgam 
1471, "soft mass formed by chemical manipulation," from M.L. amalgama, "alloy of mercury (esp. with gold or silver)," an alchemists' word, perhaps an alt. of L. malagma "poultice, plaster," from Gk. malagma "softening substance," from malassein "to soften," from malakos "soft." The word may have come from Gk. via Arabic al-malgham. Amalgamation in the figurative sense of "combining into one uniform whole" is from 1775.
