Did you know?
There are two verbs spelled "slough" in English, as well as two nouns, and both sets have different pronunciations. The first noun, referring to a swamp or a discouraged state of mind, is pronounced to rhyme with either "blue" or "cow." Its related verb, which can mean "to plod through mud," has the same pronunciation. The second noun, pronounced to rhyme with "cuff," refers to the shed skin of a snake (as well as anything else that has been cast off). Its related verb describes the action of shedding or eliminating something, just like a snake sheds its skin. This "slough" derives from Middle English "slughe" and is distantly related to a Middle High German word meaning "snakeskin."

*Indicates the sense illustrated in the example sentence.

And now I know why I have always been confused about the pronunciation of this word. Turns out there are 2 sloughs and each with a different pronunciation!
