Question: Are students influenced by a three-week course in dialectology?
Answer: “Found that students’ attitudes toward and knowledge about dialects did change as the result of teaching a three-week unit in dialectology.” EW Gratz. 1974. P. 397.
Comment: Worth noting. Two types of dialects: regional and social. The latter is considered subordinate to Standard English.
“The term dialect (from the Greek word dialektos, Διάλεκτος) is used in two distinct ways, even by linguists. One usage refers to a variety of a language that is a characteristic of a particular group of the language's speakers. The term is applied most often to regional speech patterns, but a dialect may also be defined by other factors, such as social class. The other usage refers to a language socially subordinate to a regional or national standard language, A dialect is distinguished by its vocabulary, grammar, and pronunciation (phonology, including prosody).” Wikipedia.
