Origin and history of uproot

"underground, downward-growing part of a plant," late Old English rōt and in part from a Scandinavian cognate akin to Old Norse rot "root," figuratively "cause, origin," from Proto-Germanic *wrot (source also of Old English wyrt "root, herb, plant," Old High German wurz, German Wurz "a plant," Gothic waurts "a root," with characteristic Scandinavian loss of -w- before -r-), from PIE root *wrād- "branch, root," source of a widespread PIE word-group also extending to words for plants and branches, including wort and radical. The usual Old English words for "root" were wyrttruma and wyrtwala.

Figurative use, "source of a quality or condition," is from late 12c. Of the base parts of teeth, hair, etc., from early 13c. The mathematical sense is from 1550s; the philological sense from 1520s. Slang meaning "penis" is recorded from 1846. In African-American vernacular use, "a spell effected by magical properties of roots," by 1935. The sense of "person considered as the source or offspring of a family or clan" is by early 14c., chiefly biblical.

For coveteousnes is the rote of all evylle, which whill some lusted after, they erde from the feyth, and tanglyd themselves with many sorowes. [I Timothy vi in Tyndale, 1526]

To take root is from mid-15c. as "settle in the ground," hence figurative use (by 1530s). Root beer, made from the extracts of various roots (sarsaparilla, sassafras, etc.), is recorded by 1841, American English; root doctor is from 1821. Roots "established ties with a locality or region; one's background or cultural origins" is by 1921.

"to or toward a point or place higher than another," Old English up, uppe, from Proto-Germanic *upp- "up," from PIE root *upo "under," also "up from under," hence also "over." As a preposition, from late Old English as "down onto, above and touching, sitting on, at the summit of;" from c. 1200 as "to a higher place."

Often used elliptically for go up, come up, rise up, etc. To be up to (something) "engaged in some activity" (typically reprehensible) is by 1837. Slang up the river "in jail" is recorded by 1891, originally in reference to Sing Sing, which is up the Hudson from New York City. To drive someone up the wall (1951) is from the notion of the behavior of lunatics or caged animals. Insulting retort up yours (scil. ass (n.2)) is attested by late 19c.

From the same Proto-Germanic source are Old Frisian, Old Saxon up "up, upward," Old Norse upp; Danish, Dutch op; Old High German uf, German auf "up;" Gothic iup "up, upward," uf "on, upon, under;" Old High German oba, German ob "over, above, on, upon."

"fix or firmly attach by roots" (often figurative), c. 1200, from root (n.); the sense of "pull up by the root" (now usually uproot) is from late 14c.; that of "put forth roots" is from c. 1400. Related: Rooted; rooting.
