"Amen" is a word of Hebrew origin meaning "so be it" or "truly" and it's used as a concluding statement of agreement or affirmation, particularly in religious contexts.
However, Latin phrases that convey a similar meaning include:
* "sic fiat" - "let it be so"
* "ita sit" - "so it be"
* "verum est" - "it is true"
These phrases might be used in liturgical settings or other situations where a sense of agreement or affirmation is desired.
