This document discusses dialects and their development. It defines dialects as mutually intelligible forms of a language that differ systematically. Dialects are not inferior versions of a language, as a language consists of many dialects. Regional dialects develop differences in pronunciation, vocabulary, and grammar based on geographic location. Accents reveal information about a speaker's background, while social dialects are influenced by factors like age, gender, and social situation. Standard languages aim to prevent differentiation, but many dialects like Cajun English have been banned despite being legitimate forms of communication.
