trap–bath split

The – split is a vowel split that occurs mainly in Southern English in England (including Received Pronunciation), Australian English, New Zealand English, Indian English, South African English and to a lesser extent in some Welsh English as well as older Northeastern New England English by which the Early Modern English phoneme was lengthened in certain environments and ultimately merged with the long of . In that context, the lengthened vowel in words such as ''bath'', ''laugh'', ''grass'' and ''chance'' in accents affected by the split is referred to as a ''broad A'' (also called in Britain ''long A''). Phonetically, the vowel is in Received Pronunciation (RP), Cockney and Estuary English; in some other accents, including Australian and New Zealand accents, it is a more fronted vowel ( or ) and tends to be a rounded and shortened in Broad South African English. A ''trap''–''bath'' split also occurs in the accents of the Middle Atlantic United States (New York City, Baltimore, and Philadelphia accents), but it results in very different vowel qualities to the aforementioned British-type split. To avoid confusion, the Middle Atlantic American split is usually referred to in American linguistics as a ' short-''a'' split'.

In accents unaffected by the split, words like ''bath'' and ''laugh'' usually have the same vowel as words like ''cat'', ''trap'' and ''man'': the ''short A'' or ''flat A''. Similar changes took place in words with in the ''lot–cloth'' split.

The sound change originally occurred in Southern England and ultimately changed the sound of to in some words in which the former sound appeared before . That led to RP for ''path'', for ''sample'' etc. The sound change did not occur before other consonants and so accents affected by the split preserve in words like ''cat''. (See the section below for more details on the words affected.) The lengthening of the ''bath'' vowel began in the 17th century but was "stigmatised as a Cockneyism until well into the 19th century". However, since the late 19th century, it has been embraced as a feature of upper-class Received Pronunciation.

British accents

The presence or absence of this split is one of the most noticeable differences between different accents of England. An isogloss runs across the Midlands from the Wash to the Welsh border, passing to the south of the cities of Birmingham and Leicester. North of the isogloss, the vowel in most of the affected words is usually the same short-''a'' as in ''cat''; south of the isogloss, the vowel in the affected words is generally long.

There is some variation close to the isogloss; for example in the dialect of Birmingham (the so-called ' Brummie') most of the affected words have a short-''a'', but ''aunt'' and ''laugh'' usually have long vowels. Additionally, some words which have in most forms of American English, including ''half'', ''calf'', ''rather'', ''can't'' and ''shan't'', are usually found with long vowels in the Midlands and Northern England. The split is also variable in Welsh English, often correlated with social status. In some varieties, such as Cardiff English, words like ''ask'', ''bath'', ''laugh'', ''master'' and ''rather'' are usually pronounced with while words like ''answer'', ''castle'', ''dance'' and ''nasty'' are normally pronounced with . On the other hand, the split may be completely absent in other varieties like Abercraf English.

In northern English dialects, the short A is phonetically , while the broad A varies from to ; for some speakers, the two vowels may be identical in quality, differing only in length ( vs ). John Wells has claimed that Northerners who have high social status may have a ''trap''–''bath'' split and has posted on his blog that he grew up with the split in Upholland, Lancashire. AF Gupta's study of students at the University of Leeds found that (on splitting the country in two halves) 93% of northerners used in the word 'bath' and 96% of southerners used . However, there are areas of the Midlands where the two variants co-exist and, once these are excluded, there were very few individuals in the north who had a ''trap''–''bath'' split (or in the south who did not have the split). Gupta writes, 'There is no justification for the claims by Wells and Mugglestone that this is a sociolinguistic variable in the north, though it is a sociolinguistic variable on the areas on the border he isogloss between north and south.

In some West Country accents of English English in which the vowel in ''trap'' is realised as rather than , the vowel in the ''bath'' words was lengthened to and did not merge with the of ''father''. In those accents, ''trap'', ''bath'', and ''father'' all have distinct vowels , , and .

In Cornwall, Bristol and its nearby towns, and many forms of Scottish English, there is no distinction corresponding to the RP distinction between and .

In Multicultural London English, sometimes merges with but the preceding vowel remains unchanged. That leads to the homophony between ''bath'' and ''path'' on the one hand and '' Bart'' and ''part'' on the other. Both pairs are thus pronounced and , respectively, which is not common in other non-rhotic accents of English that differentiate from . That is not categorical, and th-fronting may occur instead and so ''bath'' and ''path'' can be and instead, as in Cockney.

In Received Pronunciation

In Received Pronunciation (RP), the ''trap''–''bath'' split did not happen in all eligible words. It is hard to find a clear rule for the ones that changed. Roughly, the more common a word, the more likely that its vowel changed from flat to broad . It also looks as if monosyllables were more likely to change than polysyllables. The change very rarely took place in open syllables except if they were closely derived from another word with . Thus, for example, ''passing'' is closely derived from ''pass'' and so has broad A , while ''passage'' is not so closely derived and so has flat A . Here is the set of words that underwent transition and counterexamples with the same environment:

The split created a handful of minimal pairs, such as ant–aunt, caff–calf, cant–can't, have–halve, and staph-staff. There also are some near-minimal pairs, such as ample–sample. In accents with th-fronting (such as cockney), there are additional minimal pairs such as baff–bath and hath–half, and, in accents with th-stopping (which occurs variably in Multicultural London English), there are other minimal pairs such as bat–bath, lat–lath (with ''lat'' meaning 'latitude') and pat–path. In addition, the h-dropping in cockney creates more minimal pairs such as aff–half (with ''aff'' meaning ''affirmative'') and asp–hasp.

For the words in the last row, subsequent sound changes have altered the conditions initially responsible for lengthening.

There are some words in which both pronunciations are heard among southern speakers:

* the words ''Basque'', ''bastard'', ''chaff'', ''dastard'', ''Glasgow'', ''graph'', ''lather'', ''masque'', ''masquerade'', ''Mass'' (church service), ''pasteurise'', ''plaque'', ''plastic'', ''stance''
* Greek elements as in ''telegraph, blastocyst, chloroplast''
* words with the prefix ''trans-''

Use of broad A in ''mass'' is distinctly conservative and now rare. Other international fluctuations are common but have further complications.

While ''graph, telegraph, photograph'' can have either form (in Received Pronunciation, they now have broad A), ''graphic'' and permutations always have a flat A.

Broad A fluctuates in dialects that include it; before ''s'' it is a more common alternative when in its common voiceless variant ( rather than ) (in ''transfer'' , ''transport'' and variants) than when it is voiced (thus ''translate'' , ''trans-Atlantic'' ).

Social attitudes

Some research has concluded that many people in Northern England dislike the vowel in ''bath'' words. AF Gupta writes, 'Many of the northerners were noticeably hostile to , describing it as "comical", "snobbish", "pompous" or even "for morons"'. Writing on a Labovian study of speech in West Yorkshire, K. M. Petyt stated in 1985 that several respondents 'positively said that they did not prefer the long-vowel form or that they really detested it or even that it was incorrect'. However, Joan Beal said in a 1989 review of Petyt's work that those who disliked the pronunciation still associated it with the BBC and with the sort of professional positions to which they would aspire.

Southern Hemisphere accents

Evidence for the date of the shift comes from the Southern Hemisphere accents in Australia, New Zealand, and South Africa.

In Australian English, there is generally agreement with Southern England in words like ''path, laugh, class''. However, with the exception of South Australian English and in the specific words ''aunt, can't, shan't'' in any Australian English, other words with the vowel appearing before or , such as ''dance, plant, example'', use the flat A. Phonetically, the broad A is . In Australia, there is variation in the word ''castle'', both pronunciations being commonly heard. For more information, see the table at Variation in Australian English. In South Australian English, the broad A is usually used.

South African English and New Zealand English have a sound distribution similar to that of Received Pronunciation.

North American accents

Most accents of American English and Canadian English are unaffected by the split. The main exceptions are in extinct or older accents of eastern New England (including the early-20th-century Boston accent) and possibly the Plantation South, particularly Tidewater Virginia, where the broad sound was used in some of the same words, though usually a smaller number, as in Southern England, such as ''aunt, ask, bath''. (''Aunt'' alone still commonly uses the vowel in New England and Virginia.) By the early 1980s, the broad was in decline in New England.

Related but distinct phenomena include the following:
* The phonemic tensing of in the accents of New York English and particularly Philadelphia that occurs specifically before (in New York, tensing occurs in more environments; see /æ/ tensing).
* The drawled pronunciation in Southern accents; many South Midland, Appalachian English, and inland Southern speakers also raise the in ''aunt, dance, plant'' to or .

In North American English, the non-front realization of continental in loanwords such as ''pasta'' (cf. British ) is not an example of the trap-bath split because the vast majority of North American English accents do not feature the split in native words. Furthermore, the realization occurs regardless of the phonetic environment, even in those environments where the lengthening did not take place in the south of England, such as before a bare final in the German surname ''Mann'' (cf. British , homophonous with the native word ''man'').
