Amen

Amen is an Abrahamic declaration of affirmation which is first found in the Hebrew Bible and subsequently found in the New Testament. It is used in Jewish, Christian, and Islamic practices as a concluding word, or as a response to a prayer. Common English translations of the word amen include "verily", "truly", "it is true", and "let it be so". It is also used colloquially to express strong agreement.
