While the Italian languages, like the Aeolic dialect, gave up the dual, they retained universally the ablative which the Greeks lost, and in great part also the locative.

The rigorous logic of the Italians appears to have taken offence at the splitting of the idea of plurality into that of duality and of multitude; while they have continued with much precision to express the relations of words by inflections.

A feature peculiarly Italian, and unknown even to the Sanscrit, is the mode of imparting a substantive character to the verb by gerunds and supines,--a process carried out more completely here than in any other language.
Relation of the Italians to the Greeks These examples selected from a great abundance of analogous phenomena suffice to establish the individuality of the Italian stock as distinguished from the other members of the Indo-Germanic family, and at the same time show it to be linguistically the nearest relative, as it is geographically the next neighbour, of the Greek.
The Greek and the Italian are brothers; the Celt, the German, and the Slavonian are their cousins.

The essential unity of all the Italian as of all the Greek dialects and stocks must have dawned early and clearly on the consciousness of the two great nations themselves; for we find in the Roman language a very ancient word of enigmatical origin, -Graius-or -Graicus-, which is applied to every Greek, and in like manner amongst the Greeks the analogous appellation -- Opikos-- which is applied to all the Latin and Samnite stocks known to the Greeks in earlier times, but never to the Iapygians or Etruscans.
Relation of the Latins to the Umbro-Samnites Among the languages of the Italian stock, again, the Latin stands in marked contrast with the Umbro-Samnite dialects.

It is true that of these only two, the Umbrian and the Samnite or Oscan, are in some degree known to us, and these even in a manner extremely defective and uncertain.
