I assure you

Believe my words

I assure you is a phrase used to emphasize that what follows is true, sincere, or certain.

It functions as a verbal guarantee, adding weight to a statement the speaker wants believed: I assure you, I had nothing to do with it.

The phrase can sound formal or earnest, but also appears sarcastically when someone doubts the obvious: The feeling is mutual, I assure you.
