The meaning behind the name

All the way up to a couple of years ago, I thought the phrase actually went: "for all intensive purposes". I was reading a book when it dawned on me I had been mistaken my entire life. It made me smile.

It's great when you learn something new, and it's also great to laugh at yourself.

So, I'm not going to change. I think the phrase works just fine how I have been saying it all my life. It will just be an inside joke whenever I hear or use the phrase.
