´Cert´ for certain/ty/fy

Just a simple curiosity. Believe this should be directly intended to the americans in this forum...

Can you use ´cert´ in any way other than by force of *slang*? Or is it a plausible variation for certain/ty/ly/fy?
Asking this because I have bumped into this "(...)people can be CERT that the USA won´t (...)" in a Geography Highschool book. And it sort of jarred. This amongst many other unorthodox English inputs
Uppercase ´cert´ by me. The word had no highlight or stress whatsoever.

thanks a lot peeps!

The *only* way which I have seen "cert" used in such a fashion at all in English is as a shortened form of "certificate" or "certification" in computing contexts, where then it would be classified as jargon. I have never heard such in any kind of slang or other informal usage whatosever myself.

I agree with Travis. It was probably a typo in the textbook.
