Menén منين

Layer 1: The Coptic Engine — "Me-" (مِـ)

The Root: In the Coptic language, the absolute standard preposition used to mean "from" or "out of" is Ⲉⲓⲉⲃⲟⲗ (Ebol) or the prefix sound Ⲙⲟⲗ / Ⲙⲉ (M-/Me-).

The Adaptation: Egyptians retained the exact nasal, closed-vowel prefix مِـ (Me-) to establish the concept of origin ("from").

Layer 2: The Merged Interrogative — "-nén" (ـنِين)

The Root: As beautifully uncovered, the word فين (fén) comes directly from the Coptic locative base Ⲫⲓ (Phi / "the place") paired with a nasal question tag.

The Crossover: Egyptians took that native fén (where) concept, dropped the initial labiodental friction sound, and glued it directly onto their prefix.

When you fuse the Coptic prefix for "from" (Me-) with the modified locative pointer (-nén), you get the exact, beautifully streamlined word: منين (menén).
