Etymology 2

edit

From Middle English wrōten (“to dig with the snout”), from Old English wrōtan, from Proto-Germanic *wrōtaną (“to dig out, to root”). Related to Old English wrōt (“snout; trunk”). Loss of initial w- probably due to influence from the related noun (Etymology 1).

Verb

edit

root (third-person singular simple present roots, present participle rooting, simple past and past participle rooted)

  2. (transitive, intransitive) To turn up or dig with the snout.
    A pig roots the earth for truffles.
    • c. 1515–1516, published 1568, John Skelton, Againſt venemous tongues enpoyſoned with ſclaunder and falſe detractions &c.:
      Such tunges ſhuld be torne out by the harde rootes,
      Hoyning like hogges that groynis and wrotes.
  3. (by extension) To seek favour or advancement by low arts or grovelling servility; to fawn.
  4. (intransitive) To rummage; to search as if by digging in soil.
    Synonyms: dig out, root out, rummage

  5. (intransitive) Of a baby: to turn the head and open the mouth in search of food.
    • 2016, Rachel Waddilove, The Baby Book: How to enjoy year one: revised and updated, page 179:

  6. (transitive) To root out; to abolish.
  7. (equestrianism, of a horse) To tug or pull at the reins aggressively by driving the head downwards while wearing a bit.
  8. (Australia, New Zealand, Ireland, vulgar, slang) To sexually penetrate.
    Synonyms: screw, bang, (US) drill, (British) shag; see also Thesaurus:copulate with
Usage notes
edit
  • The Australian/New Zealand sexual sense is somewhat milder than fuck but still quite coarse, and certainly not for polite conversation. The sexual sense will often be understood, unless care is taken with the context to make the rummage sense clear, or root through or root around is used. The past participle rooted is equivalent to fucked in the figurative sense of broken or tired, but rooting has only the direct verbal sense; it is not an all-purpose intensive like fucking.
