What does insalubrious mean?
Insalubrious describes something that is unhealthy, unwholesome, or harmful to physical well-being. It is especially associated with places and conditions: an insalubrious building may have poor ventilation, inadequate sanitation, or other features that threaten the health of those who occupy it. The word can also have a broader figurative use for influences that damage social or moral well-being. Although precise and evocative, insalubrious is mainly a formal or literary term; in ordinary conversation, unhealthy, unwholesome, or harmful is generally more natural. Its uncommon status makes it useful in careful writing, where it conveys both physical danger and a broader sense of deterioration. The word should not be confused with its opposite, salubrious, which means healthy or beneficial to health.
