I've been arguing that MELEK means "king" and not "king or queen." It's interesting that Melek is also a Hebrew name for boys. Hebrew girls are evidently not named MELEK although I have not researched that particular issue with any semblance of thoroughness yet.
Here are some links that appear to support my position on MELEK:
From this site: "Every noun is either masculine or feminine. An obvious masculine noun is אישׁ (iysh - man) and an obvious feminine noun would be אשׁה (iyshah - woman). As can be seen in this example the suffix ה (ah) can be added to a masculine noun to make it feminine. Another example is the word מלך (melek - king), a masculine noun whereas מלכה (mal'khah - queen) is the feminine form."
