Clog
A
clog is a blockage in
plumbing such as hairballs, grease or other clumping materials. It is generally removed by use of a
plunger or chemical
drain cleaner.
A
clog is a
shoe with a rigid, often wooden, sole. Clogs were widely worn by workers as protective clothing in factories,
mines and farms. In more developed countries they have been replaced by steel toe-capped
boots.
A form of tap dancing using clogs is called clogging.
