Y or IE?

[DXBMermaid]

We have a dog called Indiana, Indy for short.

My MIL is called Virginia, Ginnie for short.

Are ie and y both allowed? Am not a native English speaker but can't seem to get to bottom of this as Indie and Ginny both seem accepted too.

When it comes to names, 'rules' go out of the window.

If it makes sense phonetically, it is OK.

I've noticed a lot of people (on the dreaded FB) are now spelling Mummy and Daddy as Mummie and Daddie. Is this a thing now or do I just know a lot of illiterate people?

You know a lot of illiterate people.

HTH.

It doesn't matter with names though but some names will be less interchangeable. For example, I wouldn't spell Becky as Beckie.

Thought it might be that gallic. Some
Of them make me cringe. I'm obsessed with proper spelling / grammar & feel my toes curl when I read some of the worse bits on my FB feed.
My fault for using FB I suppose.

I think it's a matter of choice, but for what it's worth, the short form/nickname for the state of Indiana is Indy.

Thank you for your replies. It seems that both are accepted as they are names.

Have been racking my brain thinking of words that are not names, and can only come up with teddy. Am I correct in thinking that the plural is teddies?

Yes it is.

Generally, the plural of any noun ending in y goes to ies.
