It occurred to me that this might be more informative if we look at it
from the opposite direction and consider movement as a parameter for
considering what is and is not an article.  Using Latin and Greek as
examples, since they're the only two free word-order languages that I'm
familiar with, we see that sentences like "That(acc) I-see man(acc)" are
perfectly legal:

Illum video virum. (Latin)
ekeínon horô: tňn ándra. (Greek)

I hear that Mohawk is the same way, as I'm sure are dozens of others.
Adjectives, quantifiers, etc. are all obviously movable.  Furthermore,
Greek usually "frames" a noun phrase with the definite article and the
noun, so the definite article comes first in the phrase and the noun
comes last.  But what is definitely *not* moveable in Greek is the
definite article itself:

*tón horô: ándra.  The(acc) I-see man(acc).

If anyone can come up with a language in which the above sentence is
grammatical, I'll be shocked.  I think it presents a universal definition
of an article as that which cannot be removed from the noun phrase.

Actually, I'll be surprised if anyone can even come up with something
that has every property of articles *except* that it can move from a noun
