YHWH is the Hebrew name for God in the Bible, also known as the Tetragrammaton. This sacred name is often referred to as the "unutterable name" as it was considered too sacred to be pronounced. Over time, various synonyms have been used to represent this name, including Adonai, Elohim, and Yah. Adonai refers to "Lord" or "Master," while Elohim is a plural form of "God," and Yah is a shortened form of YHWH. Other synonyms for YHWH include Jehovah and Yahweh, which are commonly used in Christian and Jewish texts. Despite the use of different names, they all represent the same divine being in the Abrahamic religions.
