What is meaning of amen?

Amen is an expression used at the end of a prayer, statement, or hymn to signify agreement, confirmation, or affirmation. It comes from the Hebrew word "amen" which means "so be it" or "truly." It is often used in religious settings as a way to show reverence or approval. In Christianity, saying amen at the end of a prayer or hymn is seen as a way to show one's faith and trust in God's will. Other religions, such as Judaism and Islam, also use amen as a way to express agreement or affirmation during prayer and worship.
