Thmyl Brnamj Ywr Frydwm Mhkr Alakhdr -

But the phrase length is: thmyl (5) brnamj (6) ywr (3) frydwm (6) mhkr (4) alakhdr (7)

Try “alakhdr” as target: alakhdr in plain → cipher might be each letter +n. If “alakhdr” in plain, cipher = “fqfpm iw”? No.

Try ROT-7: t(20) → 13=m h(8) → 1=a m(13) → 6=f y(25) → 18=r l(12) → 5=e Word = m a f r e → "mafre"? Not English.
