2259: mush Feb 21, 2021

Mush as an exclamation to motivate sled-dogs is obviously associated with the Far North, but is not from any Inuit Yupik language, probably. Generally the word is understood to come from French in the mid-19th century likely from an alteration of either 'marchez' or 'marchons', both being imperative forms of 'marcher' (advance; march). That said, it has also been influenced by Michif, which is a dominantly French language but with great influence from a number of various languages native to North America.
