KK: /prɪˈdɛlə/
A raised platform or step at the base of a Christian altar, often decorated with carvings or paintings that tell a story.
The artist created a beautiful predella that depicted scenes from the life of Christ.
Predella → It is formed from "prae-" (meaning before) and "della" (from Italian "della", meaning of the altar). The word refers to a platform or step before an altar, emphasizing its position in relation to the altar.
Think of a platform that is 'before' ('prae-') the altar ('della') — that's what a predella is.
