Does a scottish or irish person talk in there mind in a scottish accent or proper english?
This depends on who you are and your definition of “Proper” English To a Scot or an Irish person,the language that they communicate in is “Proper” in their minds and apart from many words in Scotland that have their roots in Doric and the Lalland speech,the same will apply to the many and varied accents within England i.e. Yorkshire,Tyne side,Birmingham and London to name but a few. If you are thinking of the English that is taught in public schools,that is just another accent. “Proper English” is the language that YOU use to communicate with others.
