How do you use the word sorriest in a sentence?

The word "sorriest" is not a commonly used word in English. It's an archaic form of "sorrowful" and is rarely used in modern English.

However, if you're looking for a way to express extreme sorrow, you could use "most sorrowful" or "deeply saddened" instead.

For example, you could say:
