Sociolinguistics is a field of study which deals mostly with language use, particularly spoken language, but not the grammatical or phonetic structure of a language. Sociolinguists do not study a language or a linguistic variety as a closed system with no reference to speaker and social life. So, Sociolinguists emphasize that language use—the sociolinguistic language system—is always variable and heterogeneous. The articles contained in this book written by the students of the Faculty of Humanities, Udayana University. The topics were raised as linguistic phenomena that are often encountered in daily interactions. Finally we do appreciate the hard effort of the students as contributors of this with their hard work. Thank you.
