What is the dialect that distinguishes British English from World English?
Yorkshire dialect The Yorkshire dialect (also Broad Yorkshire or Tyke) is a Northern English language variety spoken in England's historic county of Yorkshire. The dialect has roots in older languages such as Old English and Old Norse. The Yorkshire Dialect Society exists to promote use of the dialect in both humour and in serious linguistics; there is also an East Riding Dialect Society.
Phonemic contrast Phonemic contrast refers to a minimal phonetic difference, that is, small differences in speech sounds, that makes a difference in how the sound is perceived by listeners, and can therefore lead to different mental lexical entries for words. For example, whether a sound is voiced or unvoiced (consider /b/ and /p/ in English) matters for how a sound is perceived in many languages, such that changing this phonetic feature can yield a different word (consider "pat" and "bat" in English); see Phoneme. Other examples in English of a phonemic contrast would be the difference between "leak" and "league;" the minimal difference of voicing between [k] and [g] does lead to the two utterances being perceived as different words. On the other hand, an example that is not a phonemic contrast in English is the difference between [sit] and [siːt] . In this case the minimal difference of vowel length is not a contrast in English and so those two forms would be perceived as different pronunciations of the same word "seat".
