Etymology
Origin of weasel
before 900; 1920–25 weasel for def. 6; Middle English wesele, Old English wesle, weosule; cognate with Old High German wisula, German Wiesel
Explanation
A weasel is a sneaky and sly person. Your weasel of a friend has a habit of "forgetting" his wallet every time he goes out to dinner with you. You can call someone who cheats and lies a weasel, or you can use the word literally, to refer to the small furry mammal called a weasel. The furry kind of weasel is known for its short legs, long neck, and musky smell. In fact, the word's Proto-Germanic origin wisand carries the meaning of a stinky animal. The verb weasel means to sneak or evade, like when you weasel out of doing the dishes.
