Hello Guest, ravi,

Your words convet and Hai are not in the English language.

Go to:

http://en.wikipedia.org/wiki/Main_Page

Enter the term you want to know the meaning of, into the Search area on the left-hand side.

Enter each one separately, not together.

That way, with each of those 4 simple Wiki Searches, your troubles are over, because the answers are there already for you to read them - a wonderful way to improve your education.

Kind Regards....
