How to Pluralize Abbreviations

Pluralize abbreviations just as you would words. This means no apostrophe, with my condolences to apostrophe-lovers of the world.

Here are some examples:

I just sent the PDFs in an email.
He had two DWIs.

I know tacking the s on the end of an abbreviation like that looks kind of odd but, believe me, it's right. You'll need that apostrophe to indicate possession. Like this:

The TV's antenna was broken.
The SUV's wheel was flat.

Get it?

Got it?

Good.
