stoat

Meanings

1. 1
   noun

   Mustela erminea, the ermine or short-tailed weasel, a mustelid native to Eurasia and North America, distinguished from the least weasel by its larger size and longer tail with a prominent black tip.

   The stoat has a brown summer coat and a black-tipped tail.

From Middle English stote (“the ermine, especially in its brown summer coat”), of uncertain origin. The word bears some resemblance to Old Norse stutr (“bull”), Swedish stut (“bull, steer”) and Danish stud (“steer”) (see also English stot), but the semantic link is difficult unless a common origin is from “(brown?) male mammal”. First attested in the mid 1400s.
