Etymology: "Airbricks" is simply the plural of "airbrick," a compound of "air" and "brick." The singular names a specially perforated brick set into a wall so that air can pass through it, keeping the space behind it, such as a suspended timber floor, ventilated and drier. Because the two parts are plain English words, the term needs no foreign root to explain it: it describes exactly what the object is, a brick built to let air through.

Synonyms: vent bricks, ventilation bricks
