radicate (v.)

"cause to take root," late 15c., from Late Latin radicatus, past participle of radicare "to take root," from radix "root" (from PIE root *wrād- "branch, root"). Middle English had also radicacion (c. 1500) "fact or condition of being rooted." 

"fastened, attached, rooted," early 15c., from Late Latin radicatus, past participle of radicare "to take root," from radix "root" (from PIE root *wrād- "branch, root"). Botanical sense of "having a root" is by 1858.
