What's the proper antique equivalent to "Don't you dare"? [closed]

Solution 1:

In Shakespearean usage, thou was the nominative, and thee was the objective. This needs to be the nominative. Further, the imperative conjugation for thou was do, dare, and the indicative was dost, darest. So you would have to use do or dare.

So it would have been one of

Dare thou not,
Dare not thou,
Do not thou dare.

The position of not was flexible in Shakespeare in the imperative, so I believe all of these work. Use whichever of them you think sounds best. From Shakespeare, we have:

We will have vengeance for it, fear thou not.
Come not thou near me.
Do not you meddle; let me deal in this.

(I couldn't find a case where Shakespeare used thou in the third construction, but for Shakespeare, you and thou would have worked in the same way.)
