This paper analyzes some of the most frequent changeability processes in American slang. They may involve the change in slang with relation to standard language (from standard to slang, or vice versa), but they may also involve change within slang itself (via semantic shifts including pejoration, melioration, generalization, and specialization), as well as the appearance, disappearance, or reappearance of slang terms. This paper also discusses various types of slang with regard to language change (such as ephemeral, passive, static-core and recycled slang) and the reasons for change (such as social, generational, and other).
