I want to know the answer to the following question:
What Spanish Priest founded the Order of Preachers?
All the background I'm provided with is that "Membership in this "mendicant" order includes friars, nuns, active sisters, and lay or secular Dominicans (formerly known as tertiaries, though recently there has been a growing number of Associates, who are unrelated to the tertiaries) affiliated with the order.". Is that enough to answer the question?
