Between and Among - 2 groups or 2 items

Hi whitney,

Your post leads me to believe that you're trying to lump in an idiom rule with a pronoun rule. You also have to think about the "intent" of the sentence.

The word 'between' is used for two individuals.
The word 'among' is used for any number greater than two.

So, in your example:

"Electronic pets are more common among girls than boys."; this sentence is referencing *all* girls, which is clearly more than two. The word "among" would be the correct usage. The intent of this sentence is NOT to compare 2 individuals, it's to compare all of one group to all of another.

Yes. It's an entirely context-based difference.
