What does quatrefoil mean?
A quatrefoil is a decorative form made from four rounded lobes or leaflike sections. It appears especially in medieval and later architecture, where it may fill a circular panel, form part of a window or tracery, or provide a small carved ornament. Quatrefoils also occur in heraldry as charges with four regularly arranged lobes. The word is principally associated with detailed design rather than a natural object, and a person describing one informally might simply call it a four-leaf motif. Its compact form makes it useful in narrow spaces, and it can be rendered in materials such as stone, wood, plaster, gold, or painted metal. The name reflects the motif’s defining feature: four leaflike elements arranged around a common centre. Although often found in architecture, the quatrefoil is not limited to buildings and can also appear in manuscripts, metalwork, jewellery, furniture, and other decorative objects.

Where does quatrefoil come from?
Quatrefoil entered English from Middle English and ultimately from French, combining quatre, “four,” with a form related to foil, meaning a leaf. The French source was quatrefeuille, formed from Latin quattuor, “four,” and folium, “leaf.” The English word preserves the underlying idea of a leaflike ornament while referring specifically to a form composed of four lobes.
