time-saving
adjective
- Describing something (a device or process) that improves efficiency and reduces time needed to perform a task.
Neither "time saving" nor "time savings" should be used as a noun in the mentioned paragraph.
Rather I would suggest "Conserving time" as a far better replacement.
"time management" will be the most perfect replacement though, but it is unclear if it can be used without having more context of the matter being spoken of.
Answer from Lokenath Roy on Stack ExchangeIn this context, it would be more fitting to use "time savings." Here's a revised version:
Routing A: Time savings of 30 minutes with a probability of 50 percent.
This wording is appropriate because "time savings" is used as a noun phrase to describe the amount of time that is saved. It's expressed in the plural form to indicate a quantity of saved time.
Don't follow your gut as shown here https://www.merriam-webster.com/dictionary/time-saving the correct way to say this sentence is "Time saving of 30 minutes with a probability of 50 percent.
Time saving is singular Time savings is plural in this case it's one time saving, so routing a is the correct answer.
I know there are some words like time-saving, labor-saving, etc., but these are adjectives. I need a noun.
