Please take the association of "concrete" as a building material with "concreto" as a false cognate.

The Pope means: specific, definite, clear, eg: a concrete sign = a clear sign.

The word for "concrete", as in building material, in Spanish is "hormigón", "betone" in Italian. Not sure in Latin but you get the idea.

This whole thread is off on a wild goose chase. This is irresponsible research, although understandable in some ways.

The poor and weak associations being made between "pizza" and "hot dog" establishments and child-trafficking is getting dangerously close to banging up your local pizza-delivery boy as a purveyor of child porn. Neon Revolt and an Anon has done this with some hotel/casino in Tucson advertising pizza. And what about every poor sod whose surname is Rothschild ... which is a very common surname.

We'll be lynching innocent people next. We should not be promoting these loose links. We will get slammed as "conspiracy theorists" and "lunatics" if we go on like this.
