Expert writing Tips
Best practice
Use "for further hours" when you want to emphasize an extension of time, especially in formal or technical contexts. For example, "The experiment was extended for further hours to gather more data."
Common error
Avoid confusing "further" (used for metaphorical distance or time) with "farther" (used for physical distance). "For farther hours" would be incorrect unless referring to the physical distance traveled in those hours, which is unlikely.
