Another possibility: (A↔Z, B↔Y, etc.): n (14th letter) ↔ m (13th) — no, Atbash: n ↔ m? Wait: A(1) ↔ Z(26), B(2) ↔ Y(25), so n(14) ↔ m(13)? That’s not right — m is 13, but Atbash of n (14) = 27-14 = 13 → m. Yes.

But maybe it’s : Try ROT13 on “nwtt”: n→a, w→j, t→g, t→g → “ajgg” (not word) “aghnyt” → n→a? Actually a(1) → n(14), g(7) → t(20), h(8) → u(21), n(14) → a(1), y(25) → l(12), t(20) → g(7) → “ntualg” — no. nwtt aghnyt amy namt bkyr

One possibility is that it’s a (shift cipher) or a letter substitution . Another possibility: (A↔Z, B↔Y, etc
