The only heilkreet (cry of joy) with 7 letters is: HOSANNA
It is a Hebrew word that means “save us” or “help us.” It is often used in religious contexts as a cry of praise and supplication. It is also used in some cultures as a general expression of joy or excitement.
For example, it is used in the Bible when the people of Jerusalem cry out “Hosanna!” when Jesus enters the city on a donkey (Matthew 21:9). It is also used in the Christian hymn “Hosanna in the Highest,” which is sung on Palm Sunday.
In addition to its religious use, the word “hosanna” is also sometimes used in a more general sense to express joy or excitement. For example, it might be used by fans at a sporting event or by a crowd at a concert.
