Other forms: amalgamated; amalgamating; amalgamates
To amalgamate is to combine different things to create something new. Institutions — such as banks, schools, or hospitals — often join forces and amalgamate with one other. But other things — like musical genres — get amalgamated as well.
The verb amalgamate originally referred specifically to the mixture of metals; now however, it refers to any mixing or blending. A school board might decide to amalgamate two schools into one school due to a decrease in the student population, but amalgamating their mascots would be impossible.
