Don’t Be Despondent Over Slough and Slew

By Maeve Maddox

The spelling slough represents two meanings and two distinct pronunciations.

1. slough (rhymes with now) noun: soft, miry, muddy ground.

This is the kind of slough that John Bunyan describes in his allegory, The Pilgrim’s Progress:

Now I saw in my dream, that, just as they [Christian and Pliable] had ended this talk, they drew nigh to a very miry Slough that was in the midst of the plain; and they, being heedless, did both fall suddenly into the bog; the name of the Slough was Despond. Here, therefore, they wallowed for a time, being grievously bedaubed with the dirt; and Christian, because of the burden that was on his back, began to sink in the mire.

2. slough (rhymes with muff) noun: of a serpent or similar reptile, the cast-off skin. verb: to cast or shed the skin. Often used figuratively:

Putin, like Yeltsin, is constantly looking for ways to slough off responsibility for his decisions and their consequences…— Russia–Lost in Transition, by Liliia Fedorovna Shevtsova.

Slew, sometimes spelled slue, has more than one meaning.

The verb slew originated as a nautical term meaning “to turn a thing round upon its own axis, or without shifting it from its place. Slewed became nautical slang for “drunk” and a slew-foot was “a clumsy person who walks with feet turned out.” In Texas folklore, Pecos Bill marries a woman named “Slue-Foot Sue.”

The usual modern meaning of slew as a verb is “to turn a thing around on its own axis.” Here’s an example from fiction:

Near the top of the ramp a motorist in a gray Toyota panicked, slamming into the car behind it. Chrome and plastic hanging from its front, it slewed around blocking both lanes, effectively cutting off the Aviator. Robert Ludlum’s (TM) The Bourne Betrayal, Eric Van Lustbader.

As a noun, slew means “a very large number” or “a great amount.” For example:

Baltimore City legislators prepare for new Annapolis session with a slew of bills. City Paper, Baltimore.

A less common use of slew (also spelled slue) is in reference to “a marshy or reedy pool, pond, small lake, backwater, or inlet,” as in this description of a journey along the upper Mississippi River:

A continual variation of scene now opened to the view, marred only by an occasional ungraceful slew or marsh…

Some American speakers conflate the spelling and pronunciation of the words slough (miry ground) and slew (wetlands). They take their cue from Merriam-Webster whose entry for slough lumps the following definitions together:

1a. a place of deep mud or mire.
1b. a small marshy place.
1c. also slew or slue, a side channel or inlet

I’ll give the last word on the spelling and pronunciation of these words to The Chicago Manual of Style:

slew; slough; slue
Slew is an informal word equivalent to many or lots (you have a slew of cattle). It is sometimes misspelled slough (a legitimate noun meaning “a grimy swamp” and pronounced to rhyme with now) or slue (a legitimate verb meaning “to swing around”).

The phrase slough of despond (from Bunyan’s Pilgrim’s Progress [1678]) means a state of depression. This is etymologically different from slough (/sləf/), meaning “to discard” (slough off dry skin).

    As they say, it’s clear as mud but it covers the ground.
    -What about “slew” as the past tense of slay?
    -I never heard slough pronounced “slow” nor did I know it had an additional meaning to go with that pronunciation. I never came across that word in that context. I most often come across it in the context of something being shed, especially in the medical field, and it’s not a good thing (usually).

    I believe that there is an explanation for the use of “slew” as a very large number etc. In the Irish language (Gaelic), the word for “crowd” is “slua” and it is quite likely that the usage has transferred into English.

  • Maeve

    Here’s a post on the verb “slay” and its past tense “slew”:

    I’ve never heard “slough” pronounced as “slow” either.

  • Maeve

    You are correct. According to the OED, “slew”meaning “a large amount” does come from Irish “slua(gh),” “crowd, multitude.”

  • venqax

    @the: I don’t know of a pronunciation of slough as homophonic with the word slow. Do you mean the first definitions given here, rhyming with now? …noun: soft, miry, muddy ground.?

    Re: Some American speakers conflate [mistake] the spelling and pronunciation of the words slough (miry ground) and slew (wetlands). They take their cue from Merriam-Webster.

    A mistake propagated by MW? How routinely remarkable.

  • Donald Ulin

    I don’t think that “slough” (as in swamp) rhymes with “now” as that word is most commonly pronounced, but with “you.”

  • Maeve

    Donald Ulin,
    You are correct for the US pronunciation of slough as in “muddy ground.” US pronunciation makes slough rhyme with “you.”
    I associate the word with Bunyan’s Slough of Despond and that slough definitely rhymes with “now” in my head.

  • Katya

    Slough is NOT EVER pronounced to rhyme with ‘now.’ Like ‘sl-OWe.’ That is incorrect. It is pronounced either ‘slew’ when referring to swampy water, or ‘sloff’ – NOT rhyming with ‘muff’ – when referring to dead skin fall off. I encourage the writer of these pages to look up the CORRECT dictionary pronunciations of these words rather than using their own accented & incorrect speech

  • Maeve

    In my experience, when it comes to English usage and pronunciation, it’s best never to say “never.”

    The British place name Slough rhymes with the expletive “Ow!” And in both the OED and Merriam-Webster, the verb for a snake’s shedding its skin does rhyme with “muff.” Which dictionary do you use?
