Architects, like most professionals, use their own specialized language. Jargon in any field can be arcane, opaque and pretentious. But archispeak, unlike most other jargon, isn't usually necessary. Other, more understandable and coherent words can often be used in their place. So for instance:
WHAT DOES IT MEAN? The arrangement, proportioning, and design of windows and doors in a building.
USAGE? "The fenestration is designed to maximize daylight while providing balance to the composition of the facade"
ALTERNATIVE WORD: Windows
ALTERNATIVE USAGE? "The windows are designed to let a lot of light in and also make the front of the building really beautiful".
