amen: a one-word reply that takes another person's words and makes them binding on oneself
Amen is less a word you translate than something you do with a word. It is the spoken act of taking up what someone else has just said, a curse, an oath, a blessing, a prayer, and making it firm, valid, and binding on yourself. The same family of Hebrew words gives us the verbs for being faithful, reliable, and trustworthy, and amen carries that family's core sense of standing firm: when you say it, you let the prior words stand against you or for you.
Because it is a response rather than a statement, its force depends entirely on what it answers. Said after a curse, it accepts the curse on oneself. Said after a blessing or a prayer, it joins in and asks that the words come true. Said after a king's decree or a prophet's word, it confirms the saying as settled. The senses below are not different meanings of amen so much as the different kinds of words it can seal, but they shade into one another, which is why one short reply does the work an English speaker would split among several phrases.
The word has a striking afterlife. In its single most unusual occurrence, in Isaiah, the same word that people speak back to God becomes a name for God, the God who himself stands behind his promises. From the dust of a courtroom oath to a title for the One whose word never fails, amen travels a long way without ever quite ceasing to mean what it always meant: let it stand.
