The Hail Mary is a traditional Catholic prayer that is addressed to the Virgin Mary, the mother of Jesus.
Here are the words to the prayer:
Hail Mary, full of grace,
the Lord is with thee;
Blessed art thou among women,
and blessed is the fruit of thy womb, Jesus.
Holy Mary, Mother of God,
pray for us sinners,
now and at the hour of our death. Amen.
Note that different Catholic traditions may use slightly different versions of the prayer, but the core message and meaning remains the same. The Hail Mary is often recited as part of the Rosary, a form of Catholic prayer and meditation.
