The word "wood tar" is derived from two separate roots: "wood" and "tar".
1. Wood: The term "wood" can be traced back to the Old English word "wudu" and Proto-Germanic "widuz". It refers to the hard fibrous material that forms the stem and branches of trees and shrubs.
2. Tar: The word "tar" has a broader etymology. It is derived from the Old English "teoru", which originally referred to a resinous substance obtained from pine trees. The origin of "teoru" can be traced back to the Proto-Germanic word "*terwą". This word later evolved into various Germanic forms such as Old Norse "tjara" and Old High German "zahar". In Old Norse, it specifically referred to the black, viscous substance used as a coating for ships.
