Which term is used pejoratively for an institution for the insane?

The term that is used pejoratively for an institution for the insane is "sanatorium." Historically, sanatoriums were places where individuals with mental illnesses were often sent for treatment and care. However, over time, the term has gained a negative connotation, suggesting a lack of humane treatment or outdated methods of care, reflecting societal stigma surrounding mental health.

In contrast, a "ward" typically refers to a division within a hospital or an established area for specific types of patients but does not inherently carry pejorative connotations related to mental health. A "clinic" generally implies a facility for outpatient care and diagnosis, and it is more neutral, focusing on treatment rather than the institutionalization aspect associated with mental health. The word "hospital" is a broad and widely accepted term that denotes a place providing medical treatment for various health issues, without the stigma associated with the historical context of a sanatorium.
