I could use some help with a phrase I'm using - I'm not sure how to write it. The phrase is "We've been up and down the I's" (I is for Island). The 's looks possessive. On the other hand, using Is looks like I'm writing the word 'is'. If I use the apostrophe, will that work?
When I was in school an apostrophe + s was the way to pluralize a letter or number. For example:
You must have gone to school in the 1920's, Evil Editor.
So what if I got all C's and D's on my report card; I graduated, didn't I?
It's become acceptable to not use the apostrophe now, but I don't think that means using it is improper.
By the way, I would have had no idea what you were talking about if you hadn't told me I's meant Islands. People actually say that? Seems like it could get confusing when spoken aloud. For instance, Virginia has oddly shaped I's would mean something quite different from Virginia has oddly shaped eyes.
In short, use the apostrophe. And make sure the editor knows what the "I" stands for so she can change it to "Islands."
