A prelate is a high leader in the Christian church — a bishop, a cardinal, or another priest of that rank. It is an old, formal, slightly word. Ordinary today are more likely to say bishop or cardinal. You will meet prelate in history books, news about the Vatican, and older writing. It does not mean any priest; it means one near the top. Though actually, different churches draw the line in different places, but the core picture is the same: someone set above other clergy.
組成From Old French prelat (French prélat), from Medieval Latin praelātus, the past participle of praeferō, to carry in front or place before — a person set in front of others. The ending -ate here makes a noun for a person. It is a doublet of prefer (same Latin verb, different English path).
