This book basically deals with the types of code- switching, which are inter-sentential, intra- sentential and intra-word switching. In addition to that, constraints on the phenomenon suggested by Myers- Scotton, Matrix Language Frame constraint and Poplack, who proposed the Free-Morpheme as well as Equivalence constraint. These are applied to the song lyrics, taking a structural approach, focusing on morphological, phonological and lexical aspects. The songs are sang in two languages, English and (Lu)Ganda a language from the Niger-congo Phylum, spoken in Uganda as well as English an Indo-European language. Discover how the phenomenon of code- switching manifests itself in the two very different languages.
