* Formal: "The two sets of data were disjoint, meaning they had no elements in common."
* Informal: "My interests are disjoint from my brother's; he loves sports, and I prefer books."
* Technical: "The algorithm relies on the assumption that the input sets are disjoint."
* Figurative: "Their perspectives on the issue were disjoint, with no common ground for understanding."
Disjoint means "having no elements in common." It is often used in mathematics and computer science, but it can also be used in everyday language to describe things that are separate and distinct.
