schism

This term carries a heavy connotation of permanence and ideological conflict. It is most frequently employed in ecclesiastical or political contexts to describe a rupture that is not merely a temporary disagreement, but a formal and often hostile separation into two distinct entities. While it can describe a physical crack, this usage is rare and typically reserved for technical or geological descriptions. In most modern discourse, the word evokes a sense of betrayal or fundamental incompatibility between former allies.
