Farther vs. Further
“Farther” refers to a greater spatial distance. Think “far,” as in:
“A long time ago, in a galaxy far, far away….”
The Starship Enterprise can travel even farther than that!
“Further” is used to mean “additional” or a continuation in terms of time or degree, especially when there is no concept of distance involved.
“We need to discuss this further at our next team meeting.”
“Further, we plan to drill 18 delineation wells in the hope of extending the field farther to the west.”
In the second example above, the word “furthermore” can also be used at the beginning of the sentence.
If you’re in doubt as to whether actual distance or figurative distance is involved, it’s usually acceptable to use “further.”
Example: “Before we proceed any further, let’s re-examine the facts.”
