Tarpaper is formed from "tar" (from Old English *tær*, meaning a black, sticky substance) and "paper" (from Latin *papyrus*, meaning a writing material made from the pith of the papyrus plant). The word refers to a type of paper that is coated with tar, making it waterproof and suitable for roofing and other protective uses.
Think of 'tar' as a sticky black substance that protects, combined with 'paper' which is a material. This helps you remember that tarpaper is a protective paper coated with tar.
