So maybe last word is not ‘ender’ but ‘endet’ is nonsense. So my a=e guess fails unless asdar ≠ ‘ender’. Let’s try asdar = ‘after’? a=e? No, ‘after’ has f. So maybe a is not e.
Word wyek — maybe ‘with’? w→w? if y→i, e→t, k→h: but e is already ‘t’? But e in cipher = t? Then k→h? Possibly.
Let’s guess ttbyq = there : t→t shift 0 t→h? no, t=19, h=7 → shift -12 or +14? Better to try key guessing. Not getting clear pattern quickly. ttbyq wyak mhkr akhr asdar
Let’s check akhr = a=e, k=a, h=r, r=t → ‘e a r t’ = earth. Works with r=t. Then asdar : a=e, s=?, d=d, a=e, r=t → e ? d e t. If s=n → ‘endet’ — not English. Maybe s=‘n’ but last r=t → ‘ended’? No, that’s d at end. Actually ended = e n d e d, so last letter should be d, not t. So r cannot be t if last word is ended . Contradiction.
Now Atbash on qybtt : q→j, y→b, b→y, t→g, t→g → jbygg (no). So maybe last word is not ‘ender’ but
Shift back 5: t(19)-5=14→o, t(19)-5=14→o, b(1)-5=-4→22→w, y(24)-5=19→t, q(16)-5=11→l → ‘oowtl’ no. Try ROT13: t→g, t→g, b→o, y→l, q→d → ‘ggold’ w→j, y→l, a→n, k→x → ‘jlnx’ m→z, h→u, k→x, r→e → ‘zuxe’ a→n, k→x, h→u, r→e → ‘nxue’ a→n, s→f, d→q, a→n, r→e → ‘nfqne’
Last word asdar = e s d e r = e n d e r = ‘ender’ works if s=n, d=d, r=t? But r=t we had, but ender last letter r→t would be ‘endet’ no — contradiction: asdar last letter r=t, so asdar = e s d e t → ‘ensed’ or ‘ended’? s=n gives ‘ended’! Yes! So r→t (endet?) Wait: asdar: a=e, s=n, d=d, a=e, r=t → e n d e t — ‘endet’? Not a word. Unless last r=?? Perhaps r should be r? Then asdar = e n d e r = ‘ender’ (as in Ender’s Game). But r earlier had to = t for akhr = earth . Word wyek — maybe ‘with’
