Transpierce → It is formed from "trans-" (meaning across) and "pierce" (from Old French *percer*, meaning to penetrate or break through). The word "transpierce" means to pierce or penetrate through something across its entirety.
Think of something going 'across' ('trans-') and 'breaking through' ('pierce') — that's why transpierce means to penetrate through something.
