Question: what is the biblical meaning of hosanna?
Answer: The word hosanna (Latin osanna, Greek ὡσαννά, hōsanná) is from Hebrew הושיעה־נא, הושיעה נא hôšîʿâ-nā and related to Aramaic אושענא (ʾōshaʿnā) meaning 'save, rescue, savior'. In the Hebrew Bible it is used only in verses such as "help" or "save, I pray" (Psalms 118:25).
