Slough= is slow to rhyme with cow? or slew to rhyme with stew?

Britspeak: I'd say the first, rhyming with cow. I had a temporary brainstorm and thought it should rhyme with slow or doe (a deer, a female deer... ), but then realised I was thinking of the fruit, a sloe. Do you get them in the US? We make sloe gin, which at its best is much like the wisniowka (cherry vodka) discussed elsewhere.

Slough rhyming with cow is also the name of an English town renowned as being the back end of beyond.
With no justification at all, of course.

Fisk

Edit: after a check on Merriam-Webster, I've found I'm almost completely wrong on all fronts! I was thinking of sloughing off a skin, but that should always be pronounced sluff. And the watery meaning is slaw. D'oh.
