The story of carnival
Italian carnevale was altered from carnelevare, a formation referring to the removal of meat. The English festival name preserves its connection with the period before Lent.
The scored meanings are Italian. The Latin ancestor of levare had a raising sense; that is not the selected sense of this compound.
