| augur | auger |
| Definition:
(1) A sign of an event that is to come is an augur, whereas (2) a tool used for boring is an auger. |
| Etymology:
(1) The word augur derives from the Latin augur, the title of a Roman religious official whose role was to publicly interpret omens. (2) The word auger was coined by the faulty separation of the Middle English phrase a nauger into an auger; the former derives from the Old English nafogar, nave drill. |
