amen

Inherited from Middle English amen, from Old English āmen, from Ecclesiastical Latin āmēn, from Ancient Greek ἀμήν (amḗn), from Biblical Hebrew אָמֵן (ʾāmēn, “certainly, verily”) (cognate with Arabic آمِينَ (ʔāmīna), Classical Syriac ܐܡܝܢ (ʾāmên)).

In Old English, it was used only at the end of the Gospels; elsewhere, it was translated as sōþlīċe! (“truly, indeed!”), swā hit is (“so it is”), and sīe! (“[so] be it!”).
