Diddanydd sanctaidd tyr'd i lawr

Diddanydd sanctaidd tyr'd i lawr,
Gad i ni ganfod nefol wawr;
  Dadguddia i'n meddyliau prudd,
  Ogoniant disglaer nefol ddydd.

Disgleiria arnom Iesu cu,
Gad brofi'n hawl
    i'r nefoedd fry;
  Hosanna seiniwn beraidd gān,
  I'r Tad a'r Mab
      a'r Yspryd Glān.

Holy Comforter, come down,
Let us discern a heavenly dawn;
  Reveal to our sad thoughts,
  The radiant glory of a heavenly day.

Shine upon us, dear Jesus,
Let us experience our right
    to heaven above;
  Hosanna let us sound a sweet song,
  To the Father and the Son
      and the Holy Spirit.
