Mind has gone blank - which is correct:

[MirandaGoshawk]

They have each others' email addresses

or,
They have each other's email addresses

Is it the second one?

Bearing in mind that this is a group of people, not just two.

TIA

First one looks right but I couldn't tell you why.

I think it is the first one because others refers to more than one person. If you were referring to only two people then it would be the second one . . .i think

They have the email addresses of each other, not of each others, so it is the second one I suppose.

Hmm. They have the email address of each other, so surely 'each other's email address'. But it does look weird.

I'm now wondering if 'each other' is for two people only, and I'm confusing this with 'others'.

So for something belonging to one other person it would be other's, but for something belonging to a group it would be others'. Which complicates things in the example because each of them has his or her own email address.

Help!

I would say the second one because if you rearrange it to be "they have the email addresses of each other" then others is not the plural of other in this case (if that makes sense)

You would never say "each others" as in "they saw each others".

So you can't say "each others' email addresses".

Simple.

Oooh yes, that makes sense!

Thank you all but Minor most of all

With just two, each has the email address of the other, singular, so other's. For a group, each has the addresses of the others, plural, so others'. Autocorrect disagrees, but autocorrect talks a lot of crap at times.

How about : They each have the others' email addresses?

In that case, as others is the plural, the apostrophe would go after the s. But in your example, you would only ever say each other, not each others (as a plural) so the apostrophe should go before the s.

Mrs H, surely you could say 'They saw each others [insert apostrophe where relevant] gardens', or whatever?

my first thought was 'bottoms'

The word each surely implies a singular
So "they have the others' emaik addresses"
But "they have each orher's email address"
Each means you're considering each individually

This is about possession, after all, which isn't the case with 'they saw each other'.

The point is that you only ever pronounce an s in the possessive - they saw each other, and in the process saw each other's bottoms.

That's what I mean - there is no "each others" which could then be made possessive (the hypothetical each others').

When pondering where to put a possessive apostrophe, work out what the thing is that's doing the possessing. Pp's "of each other" reminder puts it very well.

Same reason that its' is incorrect! Cool!

I at first thought the apostrophe should be after the s, but I think the use of each changes things as others have shown. You would say:
In this school, we value each child's opinion. (Not children)
There are hundreds of mice here, but I'm not leaving until I've inspected each mouse's ears. (Not mice)

So each takes a singular and we talk about the emails of each other person.

dad it should be 'Thereare hundreds of mice here, but i am not leaving until i have inspected the ears of each mouse" grammatically you can not say mouse's ears, it's one of the exceptions to the rules, because you are right that when you talk of an object belonging to an individual (in this cases the ears to the mouse) you put the apostrophe between the individual and the 's' for example they are dad's ears .... But in english grammar you cannot say they are mouse's ears(!) because mouse is irregular so you would have to say the ears of the mouse.
miranda it is a similar thing, both your sentences look 'wrong' because grammatically they are incorrect, i think what you are trying to say is: 'all members of the group now have access to each persons email address. You do not need 'other'

Sorry i am so pedantic tbh though so long as your message is understood it shouldn't really matter

ohmy I completely disagree. What are you talking about? Of course we can talk about a mouse's ears, or each mouse's ears.

You haven't even put an apostrophe in "person's" so I can't believe you're an expert

Thanks for the back-up, Mrs H. I don't accept ohmypants point about mouse ears either.

The curse of Pedants´ Corner! I omitted an apostrophe on ohmypants

Sorry Ohmy but I'm with MrsH on this one.

Yes the argument that you can say person's but can't say mouse's makes no sense to me. Yes mouse is an irregular verb, and that affects the plural, not the possessive.
