Here's a breakdown of the word's meaning and etymology:
* "Naz" is a Persian word that means "caress," "tenderness," or "delicacy."
* "Gol" is the Persian word for "flower."
Therefore, "nazgul" literally translates to "flower of tenderness" or "tender flower," which is a stark contrast to the dark and menacing nature of these creatures in Tolkien's mythology.
The term "nazgul" is often used to refer to the entire group of wraiths, but it can also be used to refer to a single wraith.
It's important to note that "nazgul" is not a word used in everyday Persian language. It's a term that was created by Tolkien and has become associated with his works.
