Cot–caught Merger Information

The phonology of the low back vowels of the English language has undergone changes both overall and with regional variations, dating from Late Middle English (c. 1400) to the present. The sound changes heard in modern English mostly begin with the Great Vowel Shift, and continue through the development and recognition of the General American dialect and the cot-caught merger.

Late Middle English

In Late Middle English (c. 1400) the following low back vowels were present, distinguished by length:[1]

Sixteenth century changes

By 1600 the following changes had occurred:[2]

There were thus three low back monophthongs at this time: /ɔ/ as in dog, /ɔː/ as in low and (before /r/), in more and /ɒ/ in corn.

Seventeenth century changes

By 1700 the following further developments had taken place:[2]

This left the language with three low back vowels:

Father–bother merger

The father–bother merger is a merger of the Early Modern English vowels /ɑː/ and /ɒ/ that occurs in almost all varieties of North American English (exceptions are accents in northeastern New England, such as the Boston accent, and in New York City).[6][7][8] In those accents with the merger father and bother rhyme, and Kahn and con are homophonous as [kɑn]. Balm and bomb may also be homophones as /bɑm/: however this merger is prevented for some speakers by the reintroduction of the historical l into balm.[9] Another possible merger is lager and logger, for some but by no means all speakers, particularly those with the lot-cloth split when it extends to -og words including log.[10] Unrounding of EME /ɒ/ is found also in Norwich, the West Country, the West Midlands and in Hiberno-English, but apparently with no phonemic merger (typically because vowel length remains phonemic).[7] The card-cord merger is a roughly similar merger, but occurring before r.

Lot–cloth split

The lot–cloth split is the result of a late 17th century sound change that lengthened /ɒ/ to [ɒː] before voiceless fricatives, and also before /n/ in the word gone. In some accents, the lengthened [ɒː] was raised, merging with the /ɔː/ of words like thought. Words that entered the language later, or words that were used more in writing than speech, were often exempt from the lengthening, so that joss and Goth still have the short vowel.

As a result of the lengthening and raising, in the above-mentioned accents cross rhymes with sauce, and soft and cloth also have the vowel /ɔː/. Accents affected by this change include American English and, originally, RP, although today words of this group almost always have short /ɒ/ in RP. The split still exists in some older RP speakers, including Elizabeth II of the United Kingdom.

The lengthening and raising generally happened before the fricatives /f/, /θ/ and /s/. In American English the raising was extended to the environment before /ŋ/ and in a few words to the environment before /k, ɡ/ as well, giving pronunciations like /lɔŋ/ for long, /tʃɔklət/ for chocolate, and /dɔɡ/ for dog. Obviously, in accents of American English that are subject to the cot-caught merger, there is no difference between words that did and those that did not undergo the change.

In the varieties of American English that have the lot-cloth split, many words vary as to whether or not they have the cloth vowel. For example, words that end in -og like frog, hog, fog, log, bog etc. have the cloth vowel in some accents with the lot-cloth split and the lot vowel in other accents with the split.

The word gone usually has the cloth vowel in accents with the lot-cloth split, but has the lot vowel in accents of New York and New Jersey which have the split.

The word on is pronounced with the lot vowel in the North, and with the cloth vowel in the Midland, Mid-Atlantic and South.

Cot–caught merger

On this map of English-speaking North America, the green dots represent speakers who have completely merged the vowels of cot and caught. The dark blue dots represent speakers who have completely resisted the merger. The medium blue dots represent speakers with a partial merger (either production or perception but not both), and the yellow dots represent speakers with the merger in transition. Based on the work of Labov, Ash and Boberg.[8]

The cot–caught merger (also known as the low back merger) is a phonemic merger, a sound change, that occurs in some varieties of English. The merger occurs in some accents of Scottish English[7] and to some extent in Mid Ulster English[7] but is best known as a phenomenon of many varieties of North American English.

The sound change causes the vowel in caught, talk, and small to be pronounced like the vowel in cot, rock, and doll, so that cot and caught, for example, become homophones, and the two vowels merge into a single phoneme. The change does not affect a vowel followed by /r/, so barn and born remain distinct, and starring and warring do not rhyme.

The presence of the merger and its absence are both found in many different regions of the continent, and in both urban and rural environments.

The symbols traditionally used to transcribe the vowels in the words cot and caught as spoken in American English are /ɑ/ and /ɔ/, respectively, although their precise phonetic values may vary, as does the phonetic value of the merged vowel in the regions where the merger occurs.

According to Labov, Ash, and Boberg,[8] the merger does not generally occur in the southern United States (with exceptions), along most of the American side of the Great Lakes region, or in the "Northeast Corridor" extended metropolitan region from Providence, Rhode Island to Baltimore. Areas that it occurs include:[11]

The distribution of the merger is complex, even without taking into account the mobility of the American population; there are pockets of speakers with the merger in areas that lack it, and vice versa. There are areas where the merger has only partially occurred, or is in a state of transition. For example, based on research directed by William Labov (using telephone surveys), younger speakers in Kansas, Nebraska, and the Dakotas exhibit the merger while speakers older than 40 typically do not.[12] The 2003 Harvard Dialect Survey,[13] in which subjects did not necessarily grow up in the place they identified as the source of their dialect features, indicates that there are speakers of both merging and contrast-preserving accents throughout the country, though the basic isoglosses are almost identical to those revealed by Labov's 1996 telephone survey. Both surveys indicate that approximately 60% of American English speakers preserve the contrast, while approximately 40% make the merger, although in a more recent interview, Labov stated that "Half of this country has a merger of the word classes, cot, caught, don, dawn, hock, hawk."[14]

For merged speakers in Canada and most of the United States, the two sounds [ɑ] and [ɔ] are allophones; they often do not perceive differences in their usage, hear neither of them as a separate phoneme, and hear the distinct vowels used by speakers whose dialects do distinguish them as variations on the same vowel. They hear the broad A of British Received Pronunciation as the same, single vowel sound. But in Received Pronunciation, there are three sounds distinguished: the long /ɑː/ of cart, the long /ɔː/ of caught, and the short rounded /ɒ/ of cot.

Speakers with the merger in northeastern New England still maintain a phonemic distinction between a fronted and unrounded /aː/ and a back and usually rounded /ɒː/, because in northeastern New England (unlike in Canada and the Western United States), the cot-caught merger occurred without the father-bother merger. Thus, although northeastern New Englanders pronounce both cot and caught as [kɒːt], they pronounce cart as [kaːt].

Labov et al. also reveal that about 15% of respondents have the merger before /n/ but not before /t/, so that Don and Dawn are homophonous, but cot and caught are not. A much smaller group (about 4%) has the reverse situation: cot and caught are homophonous but Don and Dawn are distinct.

Speakers who have the "father-bother" merger in addition to the "cot-caught" merger may have further homophones such as ah/awe, Pa/paw, Pa's/pause-paws and shah/Shaw.

Psalm–sum merger

The psalm-sum merger is a phenomenon occurring in Singaporean English where the phonemes /ɑ/ and /ʌ/ are both pronounced [a]. As a result, pairs like "psalm" and "sum" are homophones.[citation needed]

Bud–bird merger

The bud–bird merger[citation needed] is a merger of /ɜ/ and /ʌ/ occurring for some speakers of Jamaican English making bud and bird homophones as /bʌd/.[7]

The conversion of /ɜ/ to [ʌ] or [ə] is also found in places scattered around England and Scotland. Some speakers, mostly rural, in the area from London to Norfolk exhibit this conversion, mainly before voiceless fricatives. This gives pronunciation like first [fʌst] and worse [wʌs]. The word cuss appears to derive from the application of this sound change to the word curse.
