Amen (Hebrew: אָמֵן, Amén; Arabic: آمين, Āmīn; Greek: ἀμήν, Amēn) is a declaration of affirmation found at the end of prayers, creeds, and hymns in many religions, including Judaism, Christianity, and Islam. The word is derived from the Hebrew amén, which means "so be it," "truly," or "certainly." In the context of religious practice, "Amen" is used to express agreement with or assent to what has been said or prayed. It serves as a concluding affirmation, signifying the speaker's belief in the truth or validity of the preceding statements. In Christianity, "Amen" is also used at the beginning of statements to emphasize their truthfulness, as seen in the Gospel of John, where Jesus often begins his teachings with "Amen" (or "Verily" in some translations). The use of "Amen" is deeply rooted in liturgical traditions and is a unifying element across various religious denominations.
