verbs - Words like "do/does/did" to emphasize, but for "am/is/are"

So X said to Y:

I did tell you yesterday!

As far as I know, the word did there is to emphasize my point or tell him that I'm so sure I've told him the story yesterday. What I want to ask is, what's the word we may use to emphasize our point like that in a sentence with no verb? Like

You ARE the one who breaks it!

For emphasis, I capitalized the ARE, but is there any word that functions like did does in the previous sentence?

Verily is archaic use, and thus may be used in jest or sarcasm.
