Is it 's or s'?

[Croí na hÉireann]

I am consistently annoyed at the amount of people that misuse the apostrophe every single day

This one wouldn't annoy me too much. What annoys me is the use of Their, There, They're.

One I always have to think about when writing it, is 'it's/its'.

It's a lovely day
Its colour.

Well it annoys me no end, almost as much as having missed this debate up until this point.
I think you're all right. I was with FOSB but I think Moysider makes a good point too. The problem is that the club made a balls of naming themselves.

I'm delighted to see so many posters having a very good grasp of the almost discarded apostrophe.

Mixing up Your and You're unforgivable. Seeing businesses make mistakes with the apostrophe in advertisements and the like and people adding an apostrophe before the s just for the craic in a professional setting are pretty bad.

Financial Director in my last place started every email with 'Guy's'

In the end I pulled her on it. Couldn't take it any more.

In the past, when I was sending emails to multiple parties, I was not sure how to begin salutation, if it was two I would go with "Dear Jack and Jill, if it was three I would use a ,
more than that I would go with "Hi everyone" or "To all", which sounded a bit too formal/bossy for my liking.

Anytime an email starts with "Guys," I straight away delete it. And I've never had a follow up request as to why I didn't reply or act on whatever was said. It's a great junk filter.

You're probably missing out on loads of offers and deals from Leinster Rugby.

Ah no. I read the ones that begin with "Goys".

how is this in the main thread . surely we can have a pedant and peadophile corner, if the peados don't mind sharing

[armaghniac]

Pedants have their uses, but why such fury over apostrophes?

I somehow missed this thread but glad to see Hardy and a couple of others keeping the good grammar flag flying high.  I hate to muddy the waters but can I introduce North Belfast's finest:

Patrick Pearses GAC

with the Irish version (Irish/English mash up??)

"Cumann An Phiarsaigh GAC"

CLG An Phiarsach maybe? Hardstation could say for sure.

Or maybe it is Cumann na Piarsaigh under the genetive case.

An chéad díoclaonadh:

An Piarsach = Pearse
An Phiarsaigh = Pearse's (singular genitive)
Na Piarsaigh = Pearses (plural)
Na bPiarsach = Pearses' (plural genitive)
