Jamaican Patois and Rastafarian Speech (Rasta Talk)

• Jamaican Patois

      Jamaican Patois, as most creole black languages, was originated from the contact of diffrent tribe slaves to their master (also from various places with English as language). As a variety deriving from pidgins, it incorporated the basic structure of English intermixed with a different phonological and phonetic production which can be seen sometimes as "the" greatest difference from English, confusing most people who is in touch with Jamaican culture, such as in music and poetry, who perceives just a different accent. 

       However,  there are more differences than what appears, such in grammar and lexicon.

•  Rastafarian Speech (Rasta Talk)

       Rastafarian Speech or Rasta Talk is actually a variety from the Jamaican Patois, being a religious language, with the purpose to sustain the Rastafari philosophies, it has its most peculiar charachteristic in the lexicon, for they choose to use different words in place of others considered ideologically subservient. They consider English as a colonial language, so they chose the use of words such as I always and never Me, in order to preserve the power of subjectivity of those.
