Mummerset
Mummerset is an invented English language dialect used by actors that mimics a stereotypical English Southern rural accent, while not being specific to one area.
It draws on a mix of characteristics of real accents from this region, such as strong rhotic pronunciation, forward-shifted diphthongs, lengthened vowels and dialect grammar: for instance, "I am a farmer" becomes "Oi be a faaarrrmer".
The name is a play on words: the combination of 'mummer', a slang term for a folk actor, and the name of the largely rural county of Somerset.
