What Is ‘gh’ Doing in So Many English Words?

It’s a blight, a thoroughly tough plight, enough to make you want to fight … or laugh. There are so many ways to pronounce, or not pronounce, the English "gh," almost none of which have anything to do with the usual "g" or "h" sound. Why is it there to begin with? 

Once upon a time, the "gh" did stand for a specific sound, one we don’t have in English today, except in interjections of disgust like blech. That back-of-the-throat fricative (written as /x/ in the International Phonetic Alphabet) is found in German, and if you look for the German counterpart of English "gh" words, you will often find the sound there: light ... licht, night ... nacht, eight ... acht, high ... hoch, neighbor ... nachbar, though ... doch.

So when you see a "gh," it usually means that it was pronounced with the blech sound in Old English, when our writing system was first developed. Early scribes had to adapt the Roman alphabet to English, and since Latin didn’t have the /x/ sound, they used "h" or a non-Roman character called a yogh (ȝ). Eventually, during the Middle English period, they settled on "gh."

By that time the pronunciation was already changing. The sound turned into /f/ or was dropped entirely. The Great Vowel Shift was underway and many parts of the language were in flux, but by the time the shift was complete, the printing press had stabilized the writing system, and the "gh," pointing back to an earlier English, was here to stay.

Not all examples of English "gh" can be traced back to the /x/ sound. The word-initial "gh" of ghost and ghoul came from the habits of Flemish typesetters. Words borrowed from Italian like spaghetti and ghetto just stuck with Italian spelling conventions.

And there are some words that show how "gh" took on a life of its own in English, words that came into the language long after Old English and never had a /x/ sound in them. Delight and sprightly were modified under the influence of light and right. Sleigh was made to look like weigh, perhaps to avoid looking like slay. Haughty was modeled on words like taught and aught, because, well, doesn’t that look more haughty than hawty? Like it or not, "aught" now stands for a specific pronunciation, with a rounded vowel, that really can't be spelled any other way (at least in dialects without the caught-cot merger). Is taught the same as tot or tawt? I think naught.

What is a Polar Vortex?

If you’ve turned on the news or stepped outside lately, you're familiar with the record-breaking cold that is blanketing a lot of North America. According to The Washington Post, a mass of bone-chilling air over Canada—a polar vortex—split into three parts at the beginning of 2019, and one is making its way to the eastern U.S. Polar vortexes can push frigid air straight from the arctic tundra into more temperate regions. But just what is this weather phenomenon?

How does a polar vortex form?

Polar vortexes are basically arctic hurricanes or cyclones. NASA defines them as “a whirling and persistent large area of low pressure, found typically over both North and South poles.” A winter phenomenon, vortexes develop as the sun sets over the pole and temperatures cool, and occur in the middle and upper troposphere and the stratosphere (roughly, between six and 31 miles above the Earth’s surface).

Where will a polar vortex hit?

In the Northern Hemisphere, the vortexes move in a counterclockwise direction. Typically, they dip down over Canada, but according to NBC News, polar vortexes can move into the contiguous U.S. due to warm weather over Greenland or Alaska—which forces denser cold air south—or other weather patterns.

Polar vortexes aren't rare—in fact, arctic winds do sometimes dip down into the eastern U.S.—but sometimes the sheer size of the area affected is much greater than normal.

How cold is a polar vortex?

So cold that frozen sharks have been known to wash up on Cape Cod beaches. So cold that animal keepers at the Calgary Zoo in Alberta, Canada once decided to bring its group of king penguins indoors for warmth (the species lives on islands north of Antarctica and the birds aren't used to extreme cold.) Even parts of Alabama and other regions in the Deep South have seen single-digit temperatures and wind chills below zero.

But thankfully, this type of arctic freeze doesn't stick around forever: Temperatures will gradually warm up.

In What Field Was Dr. Martin Luther King, Jr. a Doctor?

Martin Luther King, Jr. earned a doctorate in systematic theology from Boston University in 1955. He’d previously earned a Bachelor of Arts from Morehouse College and a Bachelor of Divinity from Crozer Theological Seminary. His dissertation, “A Comparison of the Conception of God in the Thinking of Paul Tillich and Henry Nelson Wieman,” examined the two religious philosophers’ views of God in comparison to each other, and to King’s own concept of a "knowable and personal" God.

Some three decades after he earned his doctorate, in 1989, archivists working with The Martin Luther King Papers Project discovered that King’s dissertation suffered from what they called a “problematic use of sources.” King, they learned, had taken a large amount of material verbatim from other scholars and sources and used it in his work without full or proper attribution, and sometimes no attribution at all.

In 1991, a Boston University investigatory committee concluded that King had indeed plagiarized parts of his dissertation, but found that it was “impractical to reach, on the available evidence, any conclusions about Dr. King's reasons for failing to attribute some, but not all, of his sources.” That is, it could have been anything from malicious intent to simple forgetfulness—no one can determine for sure today. They did not recommend a posthumous revocation of his degree, but instead suggested that a letter be attached to the dissertation in the university library noting the passages lacked quotations and citations.
