I want to know the answer to the following question:
WHat was a polish nobleman referred to as before the 15th century?
All the background I'm provided with is that "A Polish nobleman living at the time prior to the 15th century was referred to as a "rycerz", very roughly equivalent to the English "knight," the critical difference being the status of "rycerz" was almost strictly hereditary; the class of all such individuals was known as the "rycerstwo".". Is that enough to answer the question?
Answer: yes
