Is this tattoo correct?

[Puppychew]

A friend has just posted a picture of her tattoo on FB, am I correct in thinking their shouldn’t be any apostrophes?

The wording is-

Daddy’s Girl
Mama’s Angel

I don't recall being taught apostrophes at school, lots of adults can't use them properly (I teach literate and intelligent adults, I would say 50% are not confident with apostrophes) . This is a gap in the education of a generation I think.
We will be able to trust the next generation of tattooists what with all their SPAG these days.

I don't think its is an exception.

Its is the gender neutral version of his or hers therefore no apostrophe. Realising that made it a lot easier for me to get it right (assuming I am right ).

I was definitely taught at school (I'm in my 50's).

I'm a bit younger. Yes the older students are the best at it.

I'm a native speaker of English. I say box's sides and Laurence Fox's smile. So I spell them.

I don't know what style guide you're looking at. All of mine use an s if it's pronounced.

Yes string is right. If the word is already showing that the subject is plural then the apostrophe goes before the s.
So the people’s champion, the men’s toilets.

Possessive sentences like "the bag of Kate" are in the genitive case. They sound weird to our ear as Modern English doesn't really have a genitive case like, say, today's German, instead it just has the 's, which is really a possessive case, it isn't as broad. However, in Old English, there did exist this genitive case, and it was like the modern German one, i.e. it ended in 'es', hence the shortening to 's in Modern English.

Wow! Thank you all!! I understand an awful lot more now than I did earlier!!

Apostrophe’s have always confused me!

Argh! Just wrote that sentence above (and was feeling a lot clearer about the whole thing!) and then my phone has corrected my plural Apostrophes to and Apostrophe’s - why has it done this? Which one is correct? Apostrophe’s don’t own anything - it’s not ‘Apostrophe’s bag’ - and it isn’t an shortening of ‘Apostrophe is’, so why had my phone done this?

Sorry! Why HAS my phone done this?

Phones get the apostrophes wrong often, and you have to go back and correct!

I'm glad that their tattoo is correct. I know someone who had a tattoo in memory of a stillborn baby and it had a terrible grammatical error. I don't know whether anyone ever told him, I'm not sure there's a sensitive way to do that.

There could also be a situation where the exact same sentence means that Kate is a bag

Not unless the word ‘a’ is added.

A friend of mine carries around apostrophe stickers and amends signs, posters and so on. It's actually quite straight forward and until I was at Uni I didn't realise, otherwise well educated people had just never been taught how to use them.

I think here it would be better to carry around blank stickers to cover unnecessary apostrophes. I'm forever seeing signs that say things like, "Purse's for sale," it something like that. People think the apostrophe makes the word plural.

MrsHathaway - did you mean to spell Murphy's wrong ?

I work in translation and can confirm that lots of well educated and intelligent people have no idea where a comma belongs, often to the detriment of meaning.

It's was me that put Muphry's Law. And yes, it's deliberate

I know how to use their/there, will blame my phone for that one!

Thanks for the explanations, I always thought when an apostrophe was used in it’s it’s used to replace the letter i.

It I still puppy - you only ever apostrophe it’s to shorten ‘it is’, you’re correct!

Same for ‘who is’ which becomes ‘who’s’... you’d use ‘whose’ for ownership
