Let’s check ROT13 (common in puzzles): tnzyl → gaml y ? No, ROT13: t→g, n→a, z→m, y→l, l→y → gaml y (gamly?) Not English. brnamj → oeanzw no. So not ROT13.
Another idea: perhaps it’s : tnzyl reversed = lyznt no. brnamj reversed = jmanrb no. llayfwn reversed = nwf yall → nwf yall ? nwf not English. Maybe nwf = "new"? Unlikely. tnzyl brnamj viva cut mhkr llayfwn
Caesar shift (ROT) possibility: If "viva" stays as is, a shift that makes tnzyl into English might work. t → ? ; n → ? ; z → ? ; y → ? ; l → ? Let’s check ROT13 (common in puzzles): tnzyl → gaml y
