-io

A common but false misconception is that countries that end with -ia in Ido, for example Albania, use this suffix when in fact it's part of the root itself. Though, -io at times can help shape country names to fit; Mexikia uses the extra i so not to be confused with Mexiko (“Mexico City”) at the same time resembling other country names.
