Definition

Noun: 1. A window frame that is hinged on one side to open like a door: A casement is a type of window sash (the part that holds the glass) that is attached to the window frame by hinges, typically on one vertical side. It opens outward or inward by turning a crank or handle. 2. (Poetic/Literary) A window: In older or poetic usage, "casement" can refer to a window opening in a wall.

Examples of Usage

• Noun (Primary Meaning):

  • Modern casement windows are often very energy-efficient because they seal tightly when closed.
