These include "segregation," "isolation," "disintegration," "disunity," "fragmentation," "separation," "dissociation," "disjunction," and "disassociation." These words imply that elements or entities exist separately, independently, or are not compatible with each other. They may also denote a lack of collaboration, communication, or synergy between different components. While inter fusion represents unity and harmony, these antonyms suggest the opposite, indicating that entities remain distinct and divided.
