What does isolation mean?
Isolation is the condition of being separated from other people, groups, surroundings, or influences. It may be physical, as when someone is confined to a hospital room or lives in a remote place, or social and emotional, as when a person feels cut off from friends, family, and community. The word can also describe a deliberate process of setting something apart, such as isolating a sample for analysis or separating infected individuals to protect public health. Isolation does not always carry a negative meaning: privacy, concentration, and safety can all involve separation. In social contexts, however, it often suggests loneliness, exclusion, or lack of connection, making it especially important to distinguish chosen solitude from imposed or involuntary separation.

Where does isolation come from?
Isolation comes through French isolement and Italian isolare from Latin insulare, a verb meaning to make into an island. Its ultimate root is the Latin insula, meaning island, which also underlies words such as isle and insulate. The word originally developed in the sense of setting apart or making separate before acquiring its modern social and medical meanings.
