### Instruction: Why are Guyanese Creole words and phrases considered to be very elastic?
### Input: There are many sub-dialects of Guyanese Creole based on geographical location, urban - rural location, and race of the speakers. For example, along the Rupununi River, where the population is largely Amerindian, a distinct form of Guyanese Creole exists. The Georgetown (capital city) urban area has a distinct accent, while within a forty-five-minute drive away from this area the dialect/accent changes again, especially if following the coast where rural villages are located. As with other Caribbean languages, words and phrases are very elastic, and new ones can be made up, changed or evolve within a short period. They can also be used within a very small group, until picked up by a larger community. Ethnic groups are also known to alter or include words from their own backgrounds. A socially stratified creole speech continuum also exists between Guyanese English and Standard / British English. Speech by members of the upper classes is phonetically closest to British and American English, whereas speech by members of the lower classes most closely resembles other Caribbean English dialects.
