Dear teachers,

I have a question.

1) A speech disorder makes it hard for him to speak.

2) A speech disorder makes it hard him speaking.

3) A speech disorder makes it hard his speaking.

4) A speech disorder makes him speaking hard.

5) A speech disorder makes his speaking hard.

Are 2), 3), 4), and 5) grammatically correct?

And do they have the same meaning with 1)?

If not, please tell me why.

Thank you in advance.
Sincerely.
