ty, the adverb took
over its function. If we are actually justified in assuming that the
expression of all syntactic relations is ultimately traceable to these
two unavoidable, dynamic features of speech--sequence and stress[87]--an
interesting thesis results:--All of the actual content of speech, its
clusters of vocalic and consonantal sounds, is in origin limited to the
concrete; relations were originally not expressed in outward form but
were merely implied and articulated with the help of order and rhythm.
In other words, relations were intuitively felt and could only "leak
out" with the help of dynamic factors that themselves move on an
intuitional plane.

[Footnote 83: By "originally" I mean, of course, some time antedating
the earliest period of the Indo-European languages that we can get at by
comparative evidence.]

[Footnote 84: Perhaps it was a noun-classifying element of some sort.]

[Footnote 85: Compare its close historical parallel _off_.]

[Footnote 86: "Ablative" at last analysis.]

[Footnote 87: Very likely pitch should be understood along with stress.]

There is a special method for the expression of relations that has been
so often evolved in the history of language that we must glance at it
for a moment. This is the method of "concord" or of like signaling. It
is based on the same principle as the password or label. All persons or
objects that answer to the same counter-sign or that bear the same
imprint are thereby stamped as somehow related. It makes little
difference, once they are so stamped, where they are to be found or how
they behave themselves. They are known to belong together. We are
familiar with the principle of concord in Latin and Greek. Many of us
have been struck by such relentless rhymes as _vidi ilium bonum dominum_
"I saw that good master" or _quarum dearum saevarum_ "of which stern
goddesses." Not that sound-echo, whether in the form of rhyme or of
alliteration[88] is necessary to concord, though in its most typical and
original forms concord is nearly always accompanied by sound repetition.
The essence of the principle is simply this, that words (elements) that
belong together, particularly if they are syntactic equivalents or are
related in like fashion to another word or element, are outwardly marked
by the same or functionally equivalent affixes. The application of the
principle varies considerably according to the genius of the particular
language. In Latin and Greek,
