Origin

Mid 19th century: from Latin rodent- 'gnawing', from the verb rodere.

  • The teeth of rodents such as rats and mice grow continuously and must be kept worn down by gnawing, a fact that gives a clue about the origin of the term rodent. The word comes from Latin rodere ‘to gnaw’, which is related to erode (early 17th century), corrode, root, and rostrum. The original sense of the word is preserved in that unpleasant affliction the rodent ulcer.
