- tarpaulin (n.)
[tarpaulin 词源字典]
- c. 1600, evidently a hybrid from tar (n.1) + palling, from pall "heavy cloth covering" (see pall (n.)); probably so called because the canvas sometimes is coated in tar to make it waterproof. Originally tarpawlin, tarpawling, etc., the spelling settled down early 18c.[tarpaulin etymology, tarpaulin origin, 英语词源]
