Here are some examples of how it might be used in a Tudor conversation:
* "Say ye, good sir, do you think we shall have a fair harvest this year?"
* "Say ye, mistress, do you agree with the King's new laws?"
* "Say ye, my love, shall we go for a walk in the garden?"
It is a very versatile phrase, and it can be used in a variety of situations, both formal and informal.
