Conglomerateur → It is formed from "con-" (meaning together) and "glomerare" (meaning to gather or form into a ball). The word refers to someone or something that gathers or brings together various elements into a single entity.
Think of 'gathering together' ('con-') different things into one 'ball' or mass ('glomerare') — that's what a conglomerateur does.
