What does fanlight mean?
A fanlight is a semicircular or fan-shaped window positioned above a door or another window, named for the radiating glazing bars that spread from its base like the ribs of an opened hand fan. The form became a hallmark of Georgian and neoclassical architecture in Britain and Ireland during the eighteenth century, where it served both a practical purpose — admitting daylight into often narrow entrance halls and staircases — and a decorative one, lending façades a sense of balance and refinement. In American usage the term is sometimes applied more loosely to any small window over a door. Because fanlights survive on so many period townhouses, the word today appears most often in architectural description, heritage conservation, and property listings, where it signals character and historical pedigree. Its blend of function and ornament makes it a neat example of how building features acquire poetic names.

Etymology of fanlight
The word fanlight is an English compound of 'fan' and 'light', coined in the eighteenth century when such windows became fashionable; the name derives directly from the resemblance of the radiating glazing bars to the pleated ribs of a folding fan. Both parent words trace back through English, with 'light' rooted in Old English 'lēoht' and 'fan' ultimately connected to Latin 'vannus', a winnowing implement. Related forms include the fantail and other fan-shaped motifs in design.
How fanlight is actually used
The word is chiefly associated with British and Irish Georgian architecture, where it describes the distinctive semicircular overdoor window; in American usage it can denote any overdoor window. It carries connotations of elegance and period charm, appearing mostly in architectural, real-estate, and heritage contexts rather than everyday conversation.
Easily confused with fanlight
A transom is the horizontal bar or crosspiece above a door (or the window set over it), while a fanlight specifically refers to the fan-shaped window itself — the terms overlap but 'transom' covers the structural element as well.
