Etymology: Bitumen is one of those words whose ancient history is more interesting than its modern use. The Latin "bitūmen" referred to a natural, sticky substance found in the ground, and it was the same material Romans and earlier peoples used as mortar and waterproofing. Its reach into English came through Middle English, where the word appeared in forms like "bithumen" and "bitumen," so the substance has been known by this name in English for many centuries. The word also came to English with a doublet sitting beside it. "Bitume" is a related form that reached English through French, so the two words share a root but arrived by different routes. Over time, English kept the Latin-shaped spelling "bitumen" as the standard term, while the older French form faded from common use.

Synonyms: asphalt, tar, pitch, sealant, binder
