The crucifixion of Jesus is a central event in Christian belief.
Crucifixion → It is formed from "crucis" (meaning cross) and "figere" (meaning to fix or fasten). The word describes the act of fastening someone to a cross, which was a method of execution in ancient times.
Think of being 'fixed' ('figere') to a 'cross' ('crucis') — that's why crucifixion refers to the act of being nailed to a cross.
