The Etymology and Linguistic Origin of the Word 'Amen' in the Arabic Language
There have been claims that the liturgical term āmīn (Amen) derives etymologically from Amon, the chief solar deity of ancient Egypt. I found this hypothesis surprising, as Arabic differs from many languages in that native lexical items are generally analyzed within established morphological and etymological frameworks (ishtiqāq and al-wazn al-ṣarfī). Accordingly, I consulted classical Arabic linguistic sources that discuss the etymology and derivation of the word āmīn in order to examine this claim from the perspective of the Arabic grammatical tradition.
The renowned linguist Ibn Fāris states in Muʿjam Maqāyīs al-Lughah (1:133):
أمن: الهمزة والميم والنون أصلان متقاربان: أحدهما الأمانة التى هى ضدّ الخيانة، ومعناها سكون القلب، والآخر التصديق. والمعنيان كما قلنا متدانيان (...) ومن الباب الثانى – والله أعلم – قولنا فى الدعاء: آمين، قالوا: تفسيره اللهم افعل.
"The letters hamzah, mīm, and nūn (Aʾ-M-N) constitute two closely related semantic roots: one denotes trustworthiness (amānah), the opposite of betrayal, conveying the sense of tranquility of the heart; the other denotes affirmation or belief. These two meanings are closely connected. (...) From the second root—and God knows best—comes the expression āmīn used in supplication. The scholars explained it to mean: 'O God, grant [this prayer]' or 'O God, answer [it].'"
This passage indicates that āmīn is derived within the Arabic root system from the triliteral root ʾ-M-N, the same root underlying words such as amānah ("trustworthiness") and īmān ("faith, belief"). Accordingly, classical Arabic philology explains the term through the language's native morphological and semantic framework rather than as a borrowing from the name of the Egyptian deity Amon.
A similar explanation is provided by the eminent lexicographer Fīrūzābādī in al-Qāmūs al-Muḥīṭ (p. 1176):
الأمن والآمن، كصاحب: ضد الخوف، أمِنَ، كفرح. (...) وآمن به إيماناً: صدقه. (...) وآمين، بالمد والقصر، وقد يشدد الممدود ويمال أيضاً، عن الواحدي في "البسيط": اسم من أسماء الله تعالى، ومعناه: اللهم استجب، أو كذلك فليكن، أو كذلك فافعل.
"Safety (al-amn) and the secure one (al-āmin) are the opposites of fear. The verb amina follows the pattern of fariḥa. (...) The expression āmana bihi ('he believed in him/it') means 'he affirmed or deemed him truthful.' (...) As for āmīn, it may be pronounced with either a long or short initial vowel, and the long form may also occur with a geminated m. Al-Wāḥidī, in al-Basīṭ, relates that it is one of the names of God, and that its meaning is: 'O Allah, answer [this prayer],' 'So let it be,' or 'Thus do.'"
Like Ibn Fāris, Fīrūzābādī derives āmīn from the Arabic root Aʾ-M-N, associating it with the semantic field of security, trust, and belief. His explanation likewise situates the term within the native Arabic lexical and morphological tradition, rather than treating it as a borrowing from the Egyptian deity Amon.
