[El Gato]

Different words mean different things, else they wouldn't be different.

Not always. English is a very bastardized language, and one of the harder ones to learn as well. But consider:

Dog, Canine, pooch.

Swine, hog, pig.

A Native Born Citizen is not a Natural Born Citizen.

Not in modern usage, but in 1928 and for that matter 1787, they were the same.

[Windflier]

We can probably find a dictionary from 1787 and find that the words Native and Natural were clearly differentiated in that time, just as they are today.

I think we both know that those words predate the formation of our country by a very long time. They would not have both come into existence in the language if there were not a need to differentiate the two separate classes of being.

“Dog, Canine, pooch.”

All synonyms for the same thing. Not so with the two words we’re discussing, which are two distinctly different things.

[Don Corleone]

Different words mean different things, else they wouldn't be different. Not always. English is a very bastardized language, and one of the harder ones to learn as well. But consider:

Gay= happy...carfree

Gay= Fag... queer..lesbian
