What does louvre mean?
A louvre is a slatted feature fitted to a window, vent, or similar opening. Its angled blades can be fixed or adjusted to admit light and air while helping to keep out rain, insects, and debris. The word is also used as a transitive verb: to louvre a window means to fit it with louvres. British English generally uses louvre, while American English uses louver; louvred and louvered likewise follow the same regional distinction. Although now best known as a practical architectural term, louvre also has an important cultural association through the Louvre museum in Paris. The connection is reflected in the building's name, which ultimately derives from an Old French word associated with a slatted or projecting structure. In ordinary contemporary usage, however, a louvre refers specifically to the architectural device rather than to the museum. The word is especially useful when precision matters, because it identifies a particular kind of ventilated or light-admitting slatted installation more exactly than the general terms vent or shutter.
