Hosanna (/hoʊˈzænə/) is a liturgical word in Judaism and Christianity. In Judaism, it is always used in its original Hebrew form, הושענה Hoshana-Hosana.
The word hosanna (Latin osanna, Greek ὡσαννά, hōsanná) is from Hebrew הושיעה־נא, הושיעה נא hôshia-nā’ which is short for hôšî‘â-nā’ from Aramaic אושענא ('ōsha‘nā) meaning "save, rescue, savior".
In the Hebrew Bible it is used only in verses such as "help" or "save, I pray" (Psalms 118:25).
It is applied in numerous verses of the New Testament including "Hosanna; blessed is the one who comes in the name of the Lord" (Mark 11.9), "hosanna in the highest" (Mark 11.10); "hosanna to the Son of David" (Matt 21:9). The old interpretation "Save, now!", based on Psalm 118:25, does not fully explain the occurrence of the word in the Gospels as a shout of jubilation, and this has given rise to complex discussions.
