A blend of different elements or things. An amalgam is a combination or collection of things that have been combined; an assemblage of separate parts or qualities.
“What do I need to talk for, huh? What, to blab to the neighbours about how George has a new femme Jerry friend? To tell everybody at the coffee shop how George is all mixed up in a perverse sexual amalgam of some girl and his best friend? See now, I’ve done all that.”
– Cosmo Kramer
