The phrase "study at sacrilege" is a bit peculiar, as "sacrilege" means the act of violating or disrespecting something sacred or holy. However, if we were to look for synonyms for the verb "study," there are plenty of options. One could "learn," "research," "examine," "explore," "investigate," "analyze," "scrutinize," or "delve into" a subject. Each word has its own nuance and connotation, but they all speak to the act of acquiring knowledge or understanding about something. So while "study at sacrilege" may not make much sense, there are certainly plenty of ways to talk about the pursuit of knowledge.
