Hello,

I've got a question about these two verbs:"to tell" and

"to say". I know the difference in which we say " to

tell him" but " to say to him". But actually I don't

know the real difference in nature of these verbs. In

reality, when do we can use "to tell" and when do we can

use "to say"? Dosn't it matter if we use them in every

situation interchangably?

I'll be so glad if you inform me about this matter.

kind regards,
