But what does this have to do with Animals? That's the section that I'm currently in
Your sentence should rather be "वह एक बड़ा सेब है," I think. I can't quite explain the difference though. Sorry. :(
ड़, pronounced "ɽə", is a "retroflex flap." The Spanish "r", just like "र" is, pronounced "ɾ"; they are both "alveolar flaps." However, I am not sure how to explain what exactly makes "ड़" different from "ɾ."
The "retroflex" part means that the tongue is making contact with the roof of your mouth at a point farther back in your mouth than for an "alveolar" flap. It takes a bit of practice to get your tongue so far back where it sounds distinctly different, (and it might sound a bit funny at first) but you get used to it eventually.
Do any of you excellent people know how to type the ड़ symbol with google input tools? Or any other tool?
Just set your keyboard language to Hindi. Im using Gboard in which i can just switch the keyboard by one click next to my spacebar. In its settings (Hindi keyboard) you can also select that hindi letters will be shown instead of latin letters. ड़
