certain dialects of English: notably many Southern Hemisphere, North American, Irish, and 21st-century (but not older) standard Southern British accents. In speakers with this merger, the words abbot and rabbit rhyme, and Lennon and Lenin are pronounced identically, as are addition and edition. However, it is possible among these merged speakers (such as General American speakers) that a distinction is still maintained in certain contexts, such as in the pronunciation of Rosa's versus roses, due to the morpheme break in Rosa's. (Speakers without the merger generally have in the final syllables of rabbit, Lenin, roses and the first syllable of edition, distinct from the schwa heard in the corresponding syllables of abbot, Lennon, Rosa's and addition.) If an accent with the merger is also non-rhotic, then for example chatted and chattered will be homophones. The merger also affects the weak forms of some words, causing unstressed it, for instance, to be pronounced with a schwa, so that dig it would rhyme with bigot. The merger is very common in the Southern Hemisphere accents. Most speakers of Australian English (as well as recent Southern England English) replace weak with schwa, although in -ing the pronunciation is frequently ; and where there is a following , as in paddck or nomadc, some speakers maintain the contrast, while some who have the merger use as the merged vowel. In New Zealand English the merger is complete, and indeed is very centralized even in stressed syllables, so that it is usually regarded as the same phoneme as , although in -ing it is closer to [i]. In South African English most speakers have the merger, but in more conservative accents the contrast may be retained (as vs. . Plus a kit split exists; see above). The merger is also commonly found in American and Canadian English; however, the realization of the merged vowel varies according to syllable type, with appearing in word-final or open-syllable word-initial positions (such as dram or clantro), but often in other positions (abbt and xhaust). In traditional Southern American English, the merger is generally not present, and is also heard in some words that have schwa in RP, such as salad. The lack of the merger is also a traditional feature of New England English. In Caribbean English schwa is often not used at all, with unreduced vowels being preferred, but if there is a schwa, then remains distinct from
