Word Origin and History for clogged



early 14c., clogge "a lump of wood," origin unknown. Also used in Middle English of large pieces of jewelry and large testicles. Cf. Norwegian klugu "knotty log of wood." Meaning "anything that impedes action" is from 1520s. The sense of "wooden-soled shoe" is first recorded late 14c.; they were used as overshoes until the introduction of rubbers c.1840. Originally all wood (hence the name), later wooden soles with leather uppers for the front of the foot only. Later revived in fashion (c.1970), primarily for women. Clog-dancing is attested from 1863.



late 14c., "hinder," originally by fastening a block of wood to something, from clog (n.). Meaning "choke up with extraneous matter" is 17c. Related: Clogged; clogging.
