deracinate (n.)

1590s, "to pluck up by the roots," from French déraciner, from Old French desraciner "uproot, dig out, pull up by the roots," from des- (see dis-) + racine "root," from Late Latin radicina, diminutive of Latin radix "root" (from PIE root *wrād- "branch, root"). Related: Deracinated.

The French past participle, déraciné, literally "uprooted," was used in English from 1921 in a sense of "uprooted from one's national or social environment."
