f borrowing,
as in the numeral signs, it is on the part of the Etruscans, who
took over from the Romans at least the sign for 50.

Corruption of Language and Writing

Lastly it is a significant fact, that among all the Italian stocks
the development of the Greek alphabet primarily consisted in a
process of corruption. Thus the -mediae- disappeared in the whole
of the Etruscan dialects, while the Umbrians lost -"id:gamma" and
-"id:d", the Samnites -"id:d", and the Romans -"id:gamma"; and among
the latter -"id:d" also threatened to amalgamate with -"id:r".
In like manner among the Etruscans -"id:o" and -"id:u" early
coalesced, and even among the Latins we meet with a tendency to
the same corruption. Nearly the converse occurred in the case of
the sibilants; for while the Etruscan retained the three signs
-"id:z", -"id:s", -"id:sh", and the Umbrian rejected the last but
developed two new sibilants in its room, the Samnite and the Faliscan
confined themselves like the Greek to -"id:s" and -"id:z", and the
Roman of later times even to -"id:s" alone. It is plain that the
more delicate distinctions of sound were duly felt by the introducers
of the alphabet, men of culture and masters of two languages;
but after the national writing Became wholly detached from the
Hellenic mother-alphabet, the -mediae- and their -tenues- gradually
came to coincide, and the sibilants and vowels were thrown into
disorder--transpositions or rather destructions of sound, of which
the first in particular is entirely foreign to the Greek. The
destruction of the forms of flexion and derivation went hand in
hand with this corruption of sounds. The cause of this barbarization
was thus, upon the whole, simply the necessary process of
corruption which is continuously eating away every language, where
its progress is not stemmed by literature and reason; only in this
case indications of what has elsewhere passed away without leaving a
trace have been preserved in the writing of sounds. The circumstance
that this barbarizing process affected the Etruscans more strongly
than any other of the Italian stocks adds to the numerous proofs
of their inferior capacity for culture. The fact on the other hand
that, among the Italians, the Umbrians apparently were the most
affected by a similar corruption of language, the Romans less so,
the southern Sabellians least of all, probably finds its explanation,
at least in part, in the more lively intercourse
