Note: The likely home for this quotation is rotinge ger.(2), associated with roten v.(3), sense 1.(d), in all of whose quotations the word means something like 'uproot, eradicate'; its placement here is suggested by the Latin translation equivalent (exstirpare). However, this example is not quite fully at home: the remainder of the word means 'take root', and even in this obverse sense all of the examples but this one are transitive and come with attached adverbs 'root up' 'uproot' 'root adoun' 'root out'. = OED root v.1, sense group I.

Note: It is difficult to exclude the possibility of contamination between 'roten' (from 'root') and 'wroten' (wreotan = OED wroot v.); an example of 'root' with meaning derived from 'wroot' in effect belongs to OED root v.(2). MED, like OED, has divided these based on the presence of initial w-, but cp. to our example wroten v., sense 1.(c) 'to dig, work the soil' (specif. for roots), or the transitive sense 2.(c) 'to work (manure, etc.) into the soil.'
