Between vs. Among
I’m not sure if I can explain this well, but I’ll give it a shot. “Between” and “among” are used in specific situations. “Between” is correctly used when there are only two things referenced. For example,
I can’t decide between the flavors.
The above implies there are only two ice cream flavors to choose from.
I can’t decide among the flavors.
This means there are more than two flavors available.
Here’s a way to remember which word to use. Remember the phrase “just between you and me.” There are only two people involved so you use the word “between.” You can also look at the letters “tw” in the middle as a reminder that the word “two” starts with “tw” as well.
If you’re talking about more than two subjects or objects, use the word “among.”
You know the joke, “Just between you and me and the lamppost”? It’s trying to make a humorous point that the secret will remain secret. If you know the difference between “between” and “among,” you can get the linguistic level of the joke, too.
