Use of axiliary verb: common mistake

I have observed that some members are repeatedly using 'is' wrongly. For example:

Affirmative: Rama is a man.

Interrogative: Is Rama a man ?


But many are writing : "Is Rama is a man?

Here the second 'is' is superfluous.

Yes this is a mistake committed often everywhere.

Yes i too committed this mistake frequently. The given examples are useful for us Gulshanji.

Is Rama a Man?
Where have you been so long?
what is your name?
Which one among these belongs to you?
Do you love me?
Have you gone mad?

In all the above interrogative sentences, auxilliary verb comes first and then comes noun and pronoun. This is the first rule. If you remember this you won't make mistake.

These kind of mistakes usually take place due to less habit of speaking English. I feel once the grammar is learned , mistakes can also be reduced.
