Phonological history of English short A


Trap-bath split

The trap-bath split is a vowel split that occurs mainly in southern varieties of English English (including Received Pronunciation), in the Boston accent, and in the Southern Hemisphere accents (Australian English, New Zealand English, South African English), by which the Early Modern English phoneme was lengthened in certain environments and ultimately merged with the long of father.
