Well, unless you consider the so called Ebonics a language, urban African-Americans speak English. With that random (yes, random!) apostrophe J'vonte goes against the general spelling rules of English; the beginning "jv" sound combination is also not found in English. Admittedly, English is my second language, but I cannot see what English word or element J'vonte is derived from. So, I stand by my words -- J'vonte is a group of random sounds with no etymologic or liguistic significance. Maybe it has a sociologic or phychologic or some other significance, but that's another topic.
