såpass

Adverb

 * 1) to such a (high) degree; so, such, enough

Usage notes
Often strictly redundant compared to a plain. The "pass" can intuitively be thought of as "degree."

Interjection

 * 1)  to that degree(?), that much/many?, is that so?

Usage notes
Though not a natural translation, "To that degree?" should give the right idea, referring to for example quantity or how extraordinary something is.
