What is hallelujah definition?

The word hallelujah is a Hebrew term that means "praise the Lord." It is a word used in the Bible to express joy, gratitude, and reverence to God. The word "hallelujah" is derived from two Hebrew words, "hallelu" which means "praise," and "Yah," which is a shortened form of the name of God, Yahweh. The term has not only been used by Jews but also adopted by Christians and is often used during worship services and in religious music. Today, the term is often used more broadly to express joy, affirmation, or approval in secular contexts as well.
