|Look up scupper in Wiktionary, the free dictionary.|
A scupper is an opening in the side walls of an open-air structure, for purposes of draining water. They are usually placed at or near ground level, and allow rain or liquids to flow off the side of the open-air structure, instead of pooling within the walls.
There are two main kinds of scupper:
- Ships have scuppers at deck level, to allow for ocean or rainwater drain off.
- Buildings with railed rooftops can construct scuppers to let rainwater drain off, instead of pooling within the railing of the roof. Scuppers can also be placed in a parapet, for the same purpose.
The transitive verb "to scupper" (British) means to overwhelm or destroy.
