What is T'is?
Revivial of colloqial Edwardian/Victorian english. Especially abundant in Jane Austen and Bronte novels! A pleasent blend of "it is". Can sometimes sound pompous when used in an incorrect context or when speaking to div's. (see "div" or "divvy")
Pride and Prejudice Character: Oh my! Mr Darcy! T'is such a glorious day...do you not agree?
