Etymology 1[edit]

From Middle English ratte, rat, rotte, from Old English rætt, as though from Proto-Germanic *rattaz, *rattō (compare West Frisian rôt, Dutch rat), possibly from Proto-Indo-European *reh₁d- (to scrape, scratch, gnaw); however, 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 Low German ratte, radde; Middle High German rate, 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. Kroonen's explanation requires a Proto-Indo-European etymon in final *t, and is hence incompatible with the usual derivation from Proto-Indo-European *reh₁d- (to scrape, scratch, gnaw).

    • 1910, L. W. Pierce, "Muskrats are fast disappearing", in Hunter-trader-trapper, page 70:
      The price of rats began to rise and soon after the marsh froze over, spearing rats began, which was done with a one tine three-eighths inch steel rod, with a wooden handle []
    • 1929, E. J. Dailey, in Hardings Magazine's Question Box, printed in Fur Fish Game, page 73:
      Where natural marshes, or natural foods are found, are best places for raising muskrats. Louisiana and other southern states raise millions of rats, but they do not bring as good prices as northern raised ones. Delaware and Maryland have famed marshes. Other states are becoming noted for muskrat raising, also.
