Pronunciation[edit]

Etymology 1[edit]

From Middle English rat, rotte, from Old English ræt, as though from Proto-Germanic *rattaz, *rattō (compare West Frisian rôt, Dutch rat); but the rat was unknown in Northern Europe in antiquity, so if the Proto-Germanic word is real it must have referred to a different animal. Attestation of this family of words begins in the 12th century.

Some of the Germanic cognates show consonant variation, e.g. Middle High German rate, radde, ratte, ratze. The irregularity may be symptomatic of a late dispersal of the word, in which case it would not be old. Kroonen (2011) rather accounts for it with a Proto-Germanic stem *raþō nom., *ruttaz gen., showing both ablaut and a Kluge's law alternation, with the variation arising from varying remodellings in the daughters. This requires a Proto-Indo-European etymon in final *t, and is hence incompatible with the usual derivation from Proto-Indo-European *reh₁d-(to scrape).
