This is an excellent summary of a wide range of linguists theories and research and it was all I needed for the Accent and Dialect section of the AQA English Language Paper 2 Spec. I shared it with my friend who all found it succinct but detailed and ultimately very helpful with their revision and understanding the content. I hope it helps!

Well written essay that answers the practice question statement "Accent and Dialect are the most important social factors in contemporary life" well written, got a good mark
