Geechy (most commonly spelled Geechee or less often Geechie) is a name historically given to and associated with the dialect of English spoken by white people of the South Carolina low country especially in the region between Georgetown and Beaufort. A typical "Geechee" is from a family that has long resided in the area and acquired the dialect and accent in the home. There has been a movement lately to incorrectly include Geechee as a part of the "Gullah" dialect spoken by the descendants of African-American slaves in the same region and their associated culture. The geechee dialect is sometimes humorously referred to as "Charlestonese"sincec the region it is most commonly spoken is centered around Charleston, SC.
Please see Jim Reeves book titled "A Dictionary of Charlestonese" where you will find the following definitions and examples of the Geechy dialect:
Zone: his own. Toy: a piece of cloth you tie around your neck, i.e. a tie.
