Question

how can I improve my spellings in Hindi

Answer 1

Hello buddy
You know what I too faced the same problem earlier, So I made a small thin notebook of Hindi spellings and from that time whichever spelling mistakes I did, I wrote it on that notebook once a day and I really have to admit it worked. Try this and u will be getting better in Hindi, in no time!

Try to learn to pronounce and read the words correctly. 
In Hindi,we write exactly what we pronounce, so if you pronounce correctly, the chances of doing mistake automatically becomes lesser. 
Mostly people do mistake with इ and ई when applying matras, and also उ and ऊ. Once you get perfect with these, mistake ratio will fall down..

Hope it helps you..
Best wishes :-)

write the spelling you don't know and use them as much as you can , try to know the meaning of the words and write those words and spell them loudly with full focus .
