Q: There seems to be a proliferating use of the glottal stop in recent years in America. A word like “important” is pronounced as “impor-unt” To my ear at least, it sounds quite intentional and awkward, as opposed to a natural tendency to elide or soften a hard consonant. Can you shed any light on the history of this trend?
A: English speakers have been glottalizing the letter “t” since at least the mid-19th century. When the “t” is pronounced as a glottal stop, the air flow through the glottis, the area of the larynx that contains the vocal cords, stops, skips over the “t,” and is then released. The sound is often compared to the abrupt halt in the middle of the expression “Uh-oh!”
The pronunciation is common today in both American and British English. As far as we can tell, it was noted first in the UK in the mid-19th century, and in the US in the late 19th century.
The glottalization of “t” has been increasing in American English ever since. However, we haven’t noticed or seen reports of an unusual rise recently.
We suspect that the recent proliferation of “t” glottalization that you’ve sensed may be an example of the “recency illusion,” a term coined by the linguist Arnold Zwicky for “the belief that things you have noticed only recently are in fact recent.”
The earliest report of “t” glottalization we’ve found is from Visible Speech (1867), a book on phonetic notation in which the Scottish phonetician Alexander Melville Bell notes the glottal pronunciation of the “t” sound in western Scotland.
Bell, the father of Alexander Graham Bell, includes a chart entitled “Letter-Value of the Principal Consonant and Glide Symbols” that cites the pronunciation of “bu’er for butter (west of Scot.).”
Bell’s report on the use of the glottalized “t” in Scotland is cited in On Early English Pronunciation (Part 4, 1875), by Alexander John Ellis, and A Handbook of Phonetics (1877), by Henry Sweet.
In British English, the use of a glottal stop for the “t” sound in a word like “better” is now “found in many urban accents, notably London (Cockney), Leeds, Glasgow, Edinburgh and others, and is increasingly accepted among educated young people,” according to the Cambridge Pronouncing Dictionary (17th edition, 2006).
In American English, the “t” sound in a word like “butter” or “better” is usually pronounced with what linguists call a “flap” or “tap,” not with a glottal stop. This happens when the “t” follows a vowel and precedes an unstressed syllable.
The flap resembles a cross between the “t” and “d” sounds, but very much softened. An exaggerated version can be heard in movies where actors say “alligador” or “phodograph.”
The use of a glottal stop for “t” is most common in American English when the “t” comes just before an unstressed nasal syllable in words like “mitten,” “button,” “mountain,” or “important,” which sound like mi’n, bu’n, moun’n, and impor’nt.
The earliest report we’ve seen of “t” glottalization in American English is from a late 19th-century article referring to the use of the glottal stop for emphasis:
“The glottal stop is used by Americans, in general, only for the sake of extraordinary distinctness or emphasis.” From “English in America,” by the American philologist Charles Hall Grandgent, published in the German periodical Die Neueren Sprachen (The Modern Languages), February-March 1895.
However, glottalization wasn’t a significant factor in American English in the early 20th century, according to the pronunciation guide in Webster’s New International Dictionary of the English Language (1909), edited by William Torrey Harris and F. Sturges Allen:
“The glottal stop is not usually noticed as an element in English speech, but is heard in certain languages and dialects, in North German, Danish, etc.”
The dictionary notes elsewhere that glottal stops “sometimes occur as elements of speech, but are not recognized in standard English.”
A recent study of glottalization in Vermont suggests that “t” glottalization in the US began with people inserting a glottal stop just before the letter “t” to reinforce the “t” sound.
In the study, “What Goes Around: Language Change and Glottalization in Vermont” (American Speech, August 2024), the linguists Julie Roberts and Monica Nesbitt compare two samples of speech, one from the 1930s and one from the 1990s.
In the earlier sample, only the youngest of 17 speakers replaced the “t” sound with a glottal stop. That speaker, as well as older ones, sometimes reinforced the “t” with a glottal stop, a usage the authors describe as “preglottalization.”
In the later sample, the use of a glottal stop to replace or reinforce the “t” sound was more common, but not as common as the standard pronunciation of “t”—that is, a sounded or “released t.”
The authors speculate that the replacement of the “t” with a glottal stop, “present in Vermont speech today, emerged at some point not long before or during the 1930s and may have been led by younger speakers.”
As far as we can tell, Americans began commenting on the use of the glottal stop for “t” in the 1940s, suggesting that the usage was fairly prevalent by then.
In Manual of American Dialects for Radio, Stage, Screen and Television (1947), Lewis Helmar Herman and Marguerite Shalett Herman describe the use of the “glottal stop” in New England, Appalachia, the Midwest, New York City, and in Black English. Here’s an excerpt from the section on New York:
“When the sound of ‘t’ is preceded by a vowel and followed by unstressed ‘le,’ ‘on,’ ‘en,’ ‘ing,’ or ‘ain,’ it is frequently replaced by the glottal stop (/) as in ‘bA:/l’ (battle), ‘kAH/n’ (cotton), ‘mi/n’ (mitten), ‘si/n’ (sitting), or ‘suhEE/n’ (certain).”
(The authors use “/” as a symbol for the glottal stop. The usual symbol now, found in the International Phonetic Alphabet, is “ʔ” and looks like a question mark without the dot at the bottom.)
As for today, the glottalized “t” is common across the US, though some linguistic studies have shown that it’s more common in the West and is used more often by women than men.
In “T-Glottalization in American English,” a paper published in American Speech in 2009, the linguists David Eddington and Michael Taylor address the use of the glottal stop for “t” in the phrase “right ankle.”
The authors found that “younger females use glottal stops much more often than older speakers and males. Women used more glottal stops than men in every age group except one, the youngest group of males.”
Eddington and Taylor note that this finding “is consistent with a large body of sociolinguistic evidence which shows that young women tend to be on the forefront of innovative linguistic change.”
The study also “found that speakers from the western U.S. glottalized more that non-Westerners,” but added that “whether this indicates a west-to-east spread of this phonetic feature is difficult to determine without more data.”
