"Raj is a boy."
Translation:राज एक लड़का है।
The retroflex R like emrys29 mentioned sounds almost like an "r" and "d" sound right next to each other. Not entirely accurate, but a closer approximation than just an English "r." It is formed by curling your tongue back toward your throat as far as it can go (pretend like you're trying to swallow it) and then placing your tongue on the roof of your mouth. (This is true of all retroflex consonants, like ट, ठ, ड, and ढ). The sound is made by flicking it forward and comes out sounding like "aarda"
