Louvred

Part of speech: adjective

Definitions

1. An architectural term describing features with angled slats that regulate air and light while offering some protection from the outside elements
2. Referring to designs in buildings that incorporate adjustable slats to manage sunlight and airflow effectively while providing partial shelter
3. An architectural feature characterized by a series of angled openings designed to control air circulation and light entry while safeguarding interiors from harsh weather conditions

Etymology: A louver is a slatted opening angled so that air and light pass through while rain and sun are kept out. Add "-ed" and the result describes a window, shutter or roof fitted with such slats, so a louvred shutter is one that has been given louvers. "Louvred" is the British spelling of "louvered", with the same meaning. The noun it grows from is the older and more basic part, but the origin of "louver" itself is uncertain, and its route into English is not firmly established, so its ancestry is best treated as an open question.

Synonyms: slatted, vented
