Tell, though equivalent in some respects to speak and say, has not always the same application. We say, to tell this, that or what, to tell a story, to tell a word, to tell truth or falsehood, to tell a number, to tell the reasons, to tell something or nothing; but we never say, to tell a speech, discourse or oration, or to tell an argument or a lesson. It is much used in commands. Tell me the whole story; tell me all you know, or all that was said. Tell has frequently the sense of narrate; which speak and say have not.
TELL, v.i. To give an account; to make report.
--That I may publish with the voice of thanksgiving, and tell of all thy wondrous works. Ps.36.

To tell on - to inform. You must not disobey; I will tell of you if you do. This is a common popular use of the word. To tell on, is quite vulgar as well as improper.
