A rood (/ˈruːd/; abbreviation: ro[citation needed]) is a historic English and international inch-pound measure of area, as well as an archaic English measure of length.

Etymology

Rood is an archaic word for "pole", from

Proto-Germanic *rodo, cognate to Old Saxon rōda, Old High German ruoda "rod";[1] the relation of rood to rod, from Old English rodd "pole", is unclear; the latter was perhaps influenced by Old Norse
rudda "club".

In Normandy, where the rood was also used (before being replaced by metric units around 1800), it was known as a vergée, from the French word verge (stick, rod), which was borrowed in English (see virge).

(a perch being one square rod). The vergée was also a quarter of a Normandy acre, and was equal to 40 square perches (1 Normandy acre = 160 square perches).

The rood was an important measure in surveying on account of its easy conversion to acres. When referring to areas, rod is often found in old documents and has exactly the same meaning as rood.[3]

Linear measure

Rod (length)

A rood is also an obsolete British unit of linear measure between 16+1⁄2 and 24 feet (5.0–7.3 m). It is related to the German Rute and the Danish rode.[4][5] The original OED of 1914 said this sense was "now only in local use, and varying from 6 to 8 yards" (or 18 to 24 ft, "Rood", II.7).
