Try ROT+something else.
But if each word is a separate Caesar shift: thmyl brnamj ywr frydwm mhkr alakhdr
Given the time, my guess: this is a simple substitution where each letter is replaced by the next or previous in alphabet but deliberately misspelled. But “thmyl brnamj ywr frydwm mhkr alakhdr” — sounds like possibly “They will bring you freedom, maker, al-akhdar” — but “thmyl” = “they will”? thmyl → t h m y l could be t h e y w i l l if e=m? No. Try ROT+something else
But the phrase length is: thmyl (5) brnamj (6) ywr (3) frydwm (6) mhkr (4) alakhdr (7) thmyl brnamj ywr frydwm mhkr alakhdr
