Here are some examples of how "hence" is used:
* "From this place": "We walked hence to the nearest town." (meaning we walked away from our current location)
* "From this time": "Ten years hence, the world will be a very different place." (meaning in ten years from now)
* "For this reason": "The project was poorly planned, hence its failure." (meaning because of the poor planning)
Note: "Hence" is often used interchangeably with "therefore" or "thus", but it can also imply a more direct causal link.
