Tnzyl Mlf Aym Bwt Fry Fayr Here

tnzyl: t+1=u, n+1=o, z+1=a, y+1=z, l+1=m → uoazm (no) mlf: m+1=n, l+1=m, f+1=g → nmg (no) aym: a+1=b, y+1=z, m+1=n → bzn (no) bwt: b+1=c, w+1=x, t+1=u → cxu (no) fry: f+1=g, r+1=s, y+1=z → gsz (no) fayr: f+1=g, a+1=b, y+1=z, r+1=s → gbzs (no)

That yields: — doesn’t look English, so maybe it’s not Atbash. But what if it’s a Caesar shift of 1 backward (common for simple puzzles): tnzyl mlf aym bwt fry fayr

Original: t n z y l m l f a y m b w t f r y f a y r Atbash: g m a b o n o u z b n y d g u i b u z b i tnzyl: t+1=u, n+1=o, z+1=a, y+1=z, l+1=m → uoazm

t (20) → g n (14) → a z (26) → m y (25) → l l (12) → y So tnzyl → → “gamly” not English. The phrase tnzyl mlf aym bwt fry fayr

It looks like you've given a cipher or a code. The phrase tnzyl mlf aym bwt fry fayr appears to be a — possibly a shift cipher (like Caesar cipher) or an Atbash cipher (where A ↔ Z, B ↔ Y, etc.).
