# When does this determiner each modifies the plural noun?

[A] We interviewed each individual member of the community. (OALD)

For they have this meaning for ‘each’: “used to refer to every one of two or more people or things” in OALD, isn’t it proper to write [B] “~each individual members of the community~” instead of the above clause? If there isn’t the typo, can we use either singular or plural after each, for each means the individual members of a set”(CGEL, p.378)? If it’s possible, how about their meaning difference?

[C] to tell two or more people who have not met before what each other's names are (OALD)

For [C], other's names is the set, so it ought to be plural; but for [A] the community is the set, so we can't use plural form of members that is not part of the set?

Personally, I don't think [B] is possible. As for [C], I think it's 'each other's names', not 'each other's names'. Each other refers to the two or more people. –  Fantasier May 7 at 5:36

Each refers to every single member of a set individually, as opposed to all, which refers to all members of a set together. So the usage is as follows:

I gave an apple to each child in the class.
I gave an apple to all children in the class.

to tell two or more people who have not met before what each other's names are

There are several names (two or more) belonging to the people (plural) that get introduced. Here, each is not used on its own, but together with other. I agree with Fantasier that you could well use the singular here:

They got to know each other's name.
They got to know each other's names.

They sound both OK to me, but the difference is in how you parse the sentence: do you read it as:

They got to know the name of each other person. Each [other's name]
or
They got to know the names of the other people. _[Each other's] names

Simply put, I think [C] is a typo. You don't use plurals with each as a pronoun. [C] should read "each others' names are" or "each other's name is". "Each" is a singular pronoun but you'll see it used as an adverb as well, which will show plural verbs: "We were allowed two tries each." That's from M-W (http://www.merriam-webster.com/dictionary/each).
