Inter-fusion refers to the blending of two or more things, especially cultures or styles. Its opposite, antonym, is disunity or separation. Disunity occurs when individuals or groups lose their sense of togetherness and become divided. This can happen due to a variety of reasons, including political divides, cultural differences, religious tensions, or simply a lack of understanding between people. Separation occurs when people or things are kept apart from each other. This can be intentional, as seen in segregation or isolation, or it can happen naturally, as in geographical or linguistic differences. In all cases, antonyms for inter-fusion imply a sense of alienation and isolation that can be detrimental to societies and communities.
