Hosanna is a Hebrew word that means "save us." It is often used as a cry of praise or adoration, as in the case of Palm Sunday. On this day, the crowds shouted, "Hosanna! Blessed is he who comes in the name of the Lord!" (Mark 11:9). Hosanna can also be used as a prayer for help or deliverance. This is seen in Psalm 118:25, where the psalmist cries out, "Lord, save us! Lord, grant us success!" (NIV).
