The idea or belief in equality and acceptance among people of different races in a society.
Multiracialism promotes understanding and cooperation among diverse racial groups.
Multiracialism → It is formed from "multi-" (meaning many) and "racial" (from Latin "radialis", meaning of a race or lineage) and the suffix "-ism" (meaning a doctrine or belief). The term refers to the belief or doctrine that recognizes and promotes the coexistence of multiple races within a society.
Think of 'many' ('multi-') races coming together in a belief system ('-ism') — that's what multiracialism means.
