qejvi — nonsense.
t (20) ↔ g (7) h (8) ↔ s (19) m (13) ↔ n (14) y (25) ↔ b (2) l (12) ↔ o (15)
Doesn’t reveal plaintext. If we assume a simple substitution cipher where: thmyl lbt jyms bwnd llandrwyd mn mydya fayr
Result: sglxk — not meaningful.
t (20) → g (7) h (8) → u (21) m (13) → z (26) y (25) → l (12) l (12) → y (25) qejvi — nonsense
Test thmyl : t h m y l → t h m e l or t h m i l → ‘themil’ or ‘thimil’ — not a word. But thmyl could be ‘the mill’? the mill → t h e m i l l → thmyll (but we have thmyl — missing an l).
thmyl lbt jyms bwnd llandrwyd mn mydya fayr → guzly yog wlzf ojaq yyynaejql za zlqln snle — no. Search: Llandrwyd not real, but Llandrindod is. Could be Llan + drwyd (drwyd = through? in Welsh ‘drwyddo’ = through it). bwnd could be bwnd (band). jyms might be gyms . mydya might be media . t (20) → g (7) h (8) →
Better pattern: maybe it’s : each key pressed one key to the left on QWERTY.
