תרגום - אנגלית-לטינית - There is nothing like freedom.

I'm not sure we can use "tamquam" (as, just as, just like)in here, dear Alex.

This phrase needs a special sentence construction.
Compare, please:

Nothing like him = Nihil ei simile

Ok, I didn't know it.

So, is "Nihil libertati simile est" correct?

Yeap, this is just what I expected to see...
