Capsulation refers to the process of enclosing something in a capsule or container. Some synonyms for this term include encapsulation, containment, coating, envelopment, enclosure, and encasement. Encapsulation specifically refers to covering something with a protective or insulating layer, while containment involves restraining something within a space or container. Coating implies a thin layer covering the surface of an object, while envelopment suggests a more complete and thorough covering. Enclosure and encasement both involve enclosing something entirely, with encasement having a stronger connotation of protection and security. All of these synonyms reflect the idea of placing something within a protective or contained space.
