In Judaism, many different names are used for God.
One of the most important names is the Tetragrammaton. This name is made of four Hebrew letters: YHWH. It is the most common name found in the Hebrew Bible. Because it is so holy, many Jewish people do not say it out loud today. Instead, they might say "Adonai" or "HaShem," which means "The Name." During prayer, the word "Adonai" is often used to replace it. In the past, only the High Priest could say this name. He would only say it in the Holy of Holies in the Temple in Jerusalem. 
History shows that how people use these names has changed over time. In the Book of Ruth, the name was still being spoken aloud. However, by the 3rd century BCE, it had mostly stopped being spoken. Some stories say this change happened after the death of Simeon the Just. The Hebrew script used for these names is an abjad. This means the letters often do not include vowels. Later, in the medieval period, vowel points were added to the text. These points help show which words should be used when reading the holy names. 
There are several other important names used in Jewish tradition. Some lists include names like El, Elohim, Shaddai, and Tzevaot. 
Many of these names help people connect to the idea of the divine. Some names, like "Merciful" or "Gracious," are seen as descriptions of what God is like. Early scholars thought these were just descriptions rather than true names. However, some later authorities disagreed and treated them with more care. Today, these names remain a central part of how people pray and study. They help followers express respect and wonder. Whether through a special name or a quiet prayer, these words carry a lot of meaning.
In Judaism, the names used to refer to God are treated with immense sanctity. These names are not merely labels but are considered sacred entities in their own right. Because of this holiness, they are subject to specific laws regarding how they are written and spoken. For example, once a holy name is inscribed on a page, it cannot be erased. If a scribe makes an error, they must draw a line around the mistake to cancel it rather than rubbing it out. This practice ensures that the sanctity of the written word is preserved.
The most significant name is the Tetragrammaton, consisting of the four Hebrew letters YHWH. It is the most frequent name for God in the Hebrew Bible, appearing approximately 6,828 times in the Masoretic Text. The name is an abjad, meaning the original script lacks vowels. While vowels were added during the medieval period, they were often used to indicate how to substitute the name during prayer. Some scholars suggest the name is an archaic form of the verb "to be," meaning "He is" or "He will be."
Due to its extreme holiness, the pronunciation of the Tetragrammaton changed throughout history. While the Book of Ruth suggests it was spoken as late as the 5th century BCE, it had largely ceased to be pronounced aloud by the 3rd century BCE. Rabbinic tradition teaches that the name was restricted to the High Priest. He would only utter it within the Holy of Holies in the Temple of Jerusalem on Yom Kippur. Since the Temple's destruction in 70 CE, most Jews avoid the name entirely. Instead, they use substitutes like Adonai or HaShem, which means "The Name." 
Adonai is another central name, often translated as "Lord." It appears nearly 450 times in the Hebrew Bible. Grammatically, it is a possessive form of "lord" and is often viewed as a "pluralis majestatis," or a royal plural. This use of plural forms to denote a single, supreme individual is a common linguistic tool for expressing majesty. As the Tetragrammaton became too sacred to speak, Adonai became the primary verbal substitute. In many prayer books, the word Adonai is even written using two letters to avoid spelling out the actual name. 
Other important names include El, Elohim, Shaddai, and Tzevaot. The name El is often used as a generic term for a god and appears in many theophoric names, such as Michael or Gabriel. Elohim is the plural form of El, yet in the Hebrew Bible, it is almost always paired with singular verbs when referring to God. Some theologians interpret this as "the power over powers." This linguistic structure emphasizes the absolute authority of the divine. 
There has been historical debate regarding which names qualify as truly sacred. Early authorities often categorized names like "Merciful" or "Gracious" as mere epithets, or descriptions of God's character. They believed these descriptions could be written or erased without the strict rules applied to the primary names. However, later scholars like Yechiel Michel Epstein disagreed, suggesting these attributes also deserve special care. This led to an expansion of what is considered a holy name within Jewish law.
Modern Jewish practice reflects these ancient traditions through various customs of respect. Many Orthodox Jews adopt "chumras," or stringent customs, to protect the sanctity of God's name. In English, this often involves writing "G-d" instead of the full word. In Hebrew, some may use specific letter combinations to avoid writing names that could be accidentally erased. These practices connect modern believers to a long lineage of reverence that spans thousands of years. Through these names, the complex relationship between the human and the divine is expressed.
