Codecademy was filed as a trademark on September 6, 2012. When they did that there were some pre-existing similar names around (eg CA Code Academy filed on September 7, 2011). It's probably the case that they couldn't get a "Code Academy" based .com domain or something too. Plus portmanteau names for startups were trendy back then.

If it was 15 years ago it probably would have been named "Codr.io", so there is progress

Codebedandbreakfast with the YC founders saying “no that’s not quite right, how about…”

Don't for get the xylophone, ukulele, and middle aged white guy with a beard to play the mime in all the marketing material.

I had never realised that codecademy wasn't codeacadamy. Oops.

I always have issues spelling it

Can't tell if this is a joke or not.

Amigo means friend in Spanish. No more of a made up word than academy.

I believe the parent was referring to Codecademy itself.

cademy is not a word though. code cademy.

Say Codecademy and Code Academy out loud. Also in general, weird little made up words are more defensible in terms of trademarks.

And better for SEO as well, is it not?

Yeah and urls for that matter, but actually I just checked and codecademy owns codeAcademy.com

probably purchased after they started making money.

So they can copyright their name.

Names are not copyrightable; do you mean trademark?

*Trademark. Copyright protects creative works.
