The Talmud (Shabbat 89a-b) notices something strange: the mountain where Israel received the Torah is called by five different names in the Hebrew Bible. Why? Because a single mountain could not hold the weight of what happened there, and so each name preserves a different facet of a single event.
First, it was called the Wilderness of Zin — from the root tzivvui, commandment — because Israel was commanded there to observe the law. Second, the Wilderness of Kadesh, because there Israel was consecrated, made kadosh, set apart to receive the Torah. Third, the Wilderness of Kedemoth, from kedem, priority — because there Israel was given precedence over all other nations. Fourth, the Wilderness of Paran, from parah, to be fruitful — because there Israel was fruitful and multiplied in covenant. Fifth, the Wilderness of Sinai itself — from sinah, enmity — because from that moment, hostility to God's revealed truth became the burden Israel would carry among the nations.
And some sages add a sixth, which the Torah also uses: Horeb. Rabbi Abbahu derived Horeb from churban, destruction — because from Sinai came the ruin of every idolatry that pretended to be God.
One mountain. Five or six names. Because a single event of revelation commands, consecrates, elects, multiplies, and exposes — all in one thunderclap.
