Was Crocodile stronger at Marineford? Or was he holding back in Alabasta?

 During the Alabasta arc, Crocodile displayed a level of power that was initially considered overwhelming by the Straw Hat Pirates. He possessed the Logia-type Devil Fruit called the Suna Suna no Mi (Sand-Sand Fruit), which granted him the ability to control and transform into sand. He had a reputation as a Shichibukai and controlled the desert kingdom of Alabasta from the shadows. His strength was showcased through his battles with Luffy and others. At Marineford, Crocodile was present as part of the war that took place at Marine Headquarters. While he did participate in the battle, he didn't display the same level of dominance as some other powerful characters present. This has led fans to speculate that he might not have been as strong as initially portrayed in Alabasta. It's important to note that power scaling and character abilities can be subject to interpretation and development by the author. Oda often keeps details deliberately open-ended to keep the story intriguing.

Why was Greek or Latin more important for medieval scholars?

 During the Middle Ages, Latin and Greek were considered important for a number of reasons.

First, Latin was the language of the Roman Empire and, as such, was the language of law, government, and scholarship throughout much of Europe during the Middle Ages. Latin was also the language of the Catholic Church, and many religious texts, including the Bible, were translated into Latin. As a result, Latin was widely studied and spoken by scholars, clergy, and those who wanted to pursue careers in law or government.

Greek was also important during the Middle Ages because it was the language of ancient Greek philosophy and science, which had a significant influence on medieval thought. Many classical works, such as those by Aristotle and Plato, were available only in Greek, so scholars who wanted to study these works had to be proficient in the language.

In addition to being important for their own sake, Latin and Greek were also considered important because they were seen as the basis for a liberal arts education. The study of Latin and Greek was believed to help students develop critical thinking and analytical skills, as well as a broad understanding of classical culture and literature.

Overall, Latin and Greek were considered important for medieval scholars because they were the languages of law, government, religion, and classical scholarship, and because they were seen as key components of a well-rounded education.
