The ground should be completely inverted, but never do it in wet weather, as this will make the ground hard and cloggy.
A cloggy sensation of the lukewarm fat of meat is upon me (we dined an hour or two ago), and my head is as heavy as so much lead.
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.
