The phonology of the open back vowels of the English language has undergone changes both overall and with regional variations, through Old and Middle English to the present. The sounds heard in modern English were significantly influenced by the Great Vowel Shift, as well as more recent developments in some dialects such as the cot–caught merger.
Overview
Old and Middle English
In the
As the Old English (OE) system developed into that of
Later, ME
- /ɔ/, spelt ⟨o⟩, as in dog, god
- /ɔː/, often spelt ⟨oa⟩, or ⟨o⟩ before consonant+vowel or certain consonant pairs, as in boat, whole, old
16th-century changes
By 1600, the following changes had occurred:
- The long vowel /ɔː/ of boat had been raised to /oː/ as a result of the Great Vowel Shift.
- The diphthong /aw/ found in words such as cause, law, all, salt, psalm, half, change, chamber, dance had become an open back monophthong /ɔː/ or /ɑː/.
- At this time, the short /ɔ/ in dog was lowered to /ɒ/
There were thus two open back monophthongs:
- /ɒ/ as in lot
- /ɔː/ or /ɑː/ as in cause
and one open back diphthong:
- /ɔw/ as in low
17th-century changes
By 1700, the following further developments had taken place:
- The diphthong /ɔw/ of soul was raised to /ow/, and then monophthongized to /oː/, merging with boat (see African American Vernacular English.
- Short /wa/ was retracted and rounded to /wɒ/. The shift was suppressed before a Mid-Ulster English.
- /ɒ/ had begun to partake in lengthening and raising before a nonprevocalic voiceless fricative or /r/. That resulted in words like broth, cost and off having /ɒː/ instead of /ɒ/, and was the start of the LOT–CLOTH split (see further below).
- In words such as change and chamber, the pronunciation /ɔː/ was gradually replaced in the standard language by a variant with /eː/, derived from Middle English /aː/. That explains the contemporary pronunciation of these words with /eɪ/.
- However, when /ɔː/ preceded /f/, as in laugh and half, /ɔː/ was shifted to /æ/ instead, derived from Middle English /a/.
- An unrounded back vowel /ɑː/ developed, found in certain classes of words that had previously had /a/, like start, father and palm.
That left the standard form of the language with four open back vowels:
- /ɒ/ in lot and want.
- /ɒː/ in cloth and cost.
- /ɑː/ in start, father and palm.
- /ɔː/ in tor, cause, and corn.
Later changes
From the 18th century on, the following changes have occurred:
- The three-way distinction between /ɒ/, /ɒː/, and /ɔː/ was simplified in one of two ways:
- In General Americanand old-fashioned RP, /ɒː/ was raised to /ɔː/, merging with the vowel in THOUGHT (the cloth-thought merger).
- In many accents of England, the lengthening of the CLOTH set was undone, restoring the short pronunciation /ɒ/. This became standard RP by the mid-20th century.
- In
- In General American, the lot vowel has become unrounded and merged into /ɑ/ (the father–bother merger).
This leaves RP with three back vowels:
- /ɒ/ in lot, want, cloth, and cost.
- /ɔː/ in tor, cause, and corn.
- /ɑː/ in start, father, and palm.
and General American with two:
- /ɑ/ in lot, want, start, father, and palm.
- /ɔ/ in tor, cause, corn, cloth and cost.
Unrounded LOT
In a few varieties of English, the vowel in lot is unrounded, pronounced toward [ɑ]. This is found in the following dialects:
- Most of Irish English
- Much of the Caribbean
- Norwich
- The West Country and the West Midlands of England
- Most of North American English
- Excluding New England English, where it is typically raised toward /ɔ/, merging with the vowel in thought.
There's also evidence for it in South East England as early as the late 16th century and as late as the 19th century.[2][3]
Linguists disagree as to whether the unrounding of the lot vowel occurred independently in North America (probably occurring around the end of the 17th century) or was imported from certain types of speech current in Britain at that time.[citation needed]
In such accents outside of North America, lot typically is pronounced as [lɑt],[4] therefore being kept distinct from the vowel in palm, pronounced [pɑːm] or [paːm]. However, the major exception to this is North American English, where the vowel is lengthened to merge with the vowel in palm, as described below. This merger is called the LOT–PALM merger or more commonly the father–bother merger. (See further below.)
Father–bother merger
The father–bother merger is a phonemic merger of the lexical sets LOT and PALM. It represents unrounded lot, as detailed above, taken a step further. On top of being unrounded, the length distinction between the vowel in lot and bother and the vowel in palm and father is lost, so that the two groups merge. This causes father and bother to become rhymes.
This occurs in the great majority of North American accents; of the North American dialects that have unrounded lot, the only notable exception to the merger is New York City English, where the opposition with the [ɑ]-type vowel is somewhat tenuous.[5][6]
Examples of possible homophones resulting from the merger include Khan and con (/kɑn/) as well as Saab and sob (/sɑb/).[7]
While the accents in northeastern New England, such as the Boston accent, also remain unmerged, lot remains rounded and merges instead with cloth and thought.[5][6]

LOT–CLOTH split
The LOT–CLOTH split is the result of a late 17th-century sound change that lengthened /ɒ/ to [ɒː] before
The cot–caught merger, discussed below, has removed the distinction in some dialects.
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
The lengthening and raising generally happened before the fricatives /f/, /θ/ and /s/. In American English, the raising was extended to the environment before velars /ŋ/ and /ɡ/, and sometimes before /k/ as well, giving pronunciations like /lɔŋ/ for long, /dɔɡ/ for dog and /ˈtʃɔklət/ for chocolate.
In the varieties of American English that have the lot–cloth split, the lot vowel is usually symbolized as /ɑ/, often called the "short o" for historical reasons, as the corresponding RP vowel /ɒ/ is still short (and it contrasts with /ɑː/ as in father and start). The thought vowel is usually transcribed as /ɔ/ and it is often called the "open o". Its actual phonetic realization may be open [ɒ], whereas the lot vowel may be realized as central [ä]. Some words vary as to which vowel they have. For example, words that end in -og like frog, hog, fog, log, bog etc. have /ɑ/ rather than /ɔ/ in some accents.
There are also significant complexities in the pronunciation of written o occurring before one of the triggering phonemes /f θ s ŋ ɡ/ in a non-final syllable. However, the use of the open o as opposed to the short o is largely predictable. Just like with

Other changes
GOAT–THOUGHT merger
The GOAT–THOUGHT merger is a merger of the English vowels /oʊ/ and /ɔː/ that occurs in Bradford English and sometimes also in Geordie and Northern Welsh English.
THOUGHT–FOOT-GOOSE merger
The THOUGHT–FOOT merger is a merger of the English vowels /ɔː/ and /ʊ/ that occurs in morphologically closed syllables in Cockney, rendering fought homophonous with foot as [ˈfʊʔ]. It is possible only in fast speech.
The THOUGHT–GOOSE merger is a merger of the English vowels /ɔː/ and /uː/ that occurs in Cockney, rendering hoard homophonous with who'd as [ˈʊd], with the vowel quality that is typical of FOOT. It is possible only in fast speech and, in the case of /ɔː/ (but not /uː/), only in morphologically closed syllables.
THOUGHT split
In some London accents of English, the vowel in words such as thought, force, and north, which merged earlier on in these varieties of English, undergoes a conditional split based on syllable structure: closed syllables have a higher vowel quality such as [oː] (possibly even [oʊ] in broad Cockney varieties), and open syllables have a lower vowel quality [ɔ̝ː] or a centering diphthong [ɔə].
Originally-open syllables with an inflectional suffix (such as bored) retain the lower vowel quality, creating minimal pairs such as bored [bɔəd] vs. board [boːd].[21]
In broad Geordie, some THOUGHT words (roughly, those spelled with a, as in walk and talk) have [aː] (which phonetically is the long counterpart of TRAP /a/) instead of the standard [ɔː]. Those are the traditional dialect forms which are being replaced with the standard [ɔː]. [aː] is therefore not necessarily a distinct phoneme in the vowel system of Geordie, also because it occurs as an allophone of /a/ before voiced consonants.[22]
Distribution of /ɑː/
The distribution of the vowel transcribed with ⟨ɑː⟩ in broad IPA varies greatly among dialects. It corresponds to /æ/, /ɒ/, /ɔː/ and (when not prevocalic within the same word) /ɑːr/ and even /ɔːr/ in other dialects:
- In non-rhotic dialects spoken outside of North America, /ɑː/ corresponds mostly to /ɑːr/ in General American and so is most often spelled ⟨ar⟩. In dialects with the trap–bath split (such as Received Pronunciation, New Zealand English and South African English), it also corresponds to GA /æ/, which means that it can also be spelled ⟨a⟩ before voiceless fricatives. In those dialects, /ɒ/ and /ɔː/ are separate phonemes.
- In native words, /ɑː/ in most non-rhotic speech of North America corresponds to both /ɑːr/ in GA (RP /ɑː/) and /ɒ/ in RP, as those dialects feature the father–bother merger.
- North American English features the father–bother merger, where /ɑː/ often corresponds to /ɒ/ in RP. Only New York City English and New England English distinguish between the two, and with an unrounded LOT vowel. Modern-day New York City English also has rounded /ɒː/ for reflexes of PALM, which ironically, came from an unrounded vowel.
- The is the Pittsburgh English.
- The caught-cot merger without the father-bother merger is found in Scottish English and most of New England English. Uniquely, Scottish English merges the LOT vowel into the THOUGHT vowel, rather than the other way around.
- In loanwords and names, the open central unrounded vowel [ä] in a source language is regularly approximated with /ɑ(ː)/ in North America and /æ/ in RP. However, in the case of mid back rounded vowels spelled ⟨o⟩, the usual North American approximation is /oʊ/, not /ɑː/ (in RP, it can be either /əʊ/ or /ɒ/). However, when the vowel is both stressed and word-final, the only possibilities in RP are /ɑː/ in the first case and /əʊ/ in the latter case, mirroring GA.
For the sake of simplicity, instances of an unrounded LOT vowel (phonetically [ɑ]) that do not merge with PALM/START are excluded from the table below. For this reason, the traditional Norfolk dialect is included but the contemporary one, nor the Cardiff dialect, are not.

Fronted /oʊ/
In many dialects of English, the vowel /oʊ/ has undergone fronting. The exact phonetic value varies. Dialects with the fronted /oʊ/ include Received Pronunciation; Southern, Midland, and Mid-Atlantic American English; and Australian English. This fronting does not generally occur before /l/, a relatively retracted consonant.
