Yet another myth about the English language: among versus between
Subtitle:
Common mistakes seen on italki. Mistake #2: Misuse of AMONG.
Let's start with a question. Which of the following two options is correct?
A What's the difference between X, Y and Z?
B What's the difference among X, Y and Z?
Hands up. Who thinks B is correct?
If you think is B is correct, you're almost certainly a non-native speaker of English. You chose option B because your teacher or grammar book taught you to use 'between' when there are two elements and 'among' when there are more than two. You think that option A is wrong, because you shouldn't use 'between' when you're talking about three things. Is that the case?
Well, unfortunately, this 'rule' is one of the many myths about English, one of the many 'facts' that are taught to millions worldwide but which turn out to be wrong.
In fact, the correct wording is "What is the difference between X, Y and Z?". This is because you are asking us to consider each of these elements individually, and to identify the difference between X and Y, between X and Z, and between Y and Z. You cannot use 'among' in this context.
Here's a dictionary definition of 'among':
1: in the middle of or surrounded by other things
The flowers are hidden among the roots of the trees
Detectives searched among the wreckage for evidence
2: happening or being included as part of a group of people or things
The problem is most widespread among teenagers
A 20-year-old Canadian woman is among the victims
Those are correct examples of how to use 'among'.
Remember - the difference between 'among' and 'between' is not merely a question of number and it is always wrong to say 'the difference among..."
