European speech, in respect of their most significant differences, ranges itself thus:
(i.) Back-palatal and Velar Sounds.—In point of its treatment of the Indo-European back-palatal and velar sounds, it belongs to the western or centum group, the name of which is, of course, taken from Latin; that is to say, like German, Celtic and Greek, it did not sibilate original k and g, which in Indo-Iranian, Armenian, Slavonic and Albanian have been converted into various types of sibilants (Ind.-Eur.* km̥tom = Lat. centum, Gr. (ἑ)-κατόν, Welsh cant, Eng. hund-(red), but Sans. ṧatam, Zend satəm); but, on the other hand, in company with just the same three western groups, and in contrast to the eastern, the Italic languages labialized the original velars (Ind.-Eur. * qod = Lat. quod, Osc. pod, Gr. ποδ-(απός), Welsh pwy, Eng. what, but Sans. kás, “who?”).
(ii.) Indo-European Aspirates.—Like Greek and Sanskrit, but in contrast to all the other groups (even to Zend and Armenian), the Italic group largely preserves a distinction between the Indo-European mediae aspiratae and mediae (e.g. between Ind.-Eur. dh and d, the former when initial becoming initially regularly Lat. f as in Lat. fēc-ī [cf. Umb. feia, “faciat”], beside Gr. ἔ-θηκ-α [cf. Sans. da-dhā-ti, “he places”], the latter simply d as in domus, Gr. δόμος). But the aspiratae, even where thus distinctly treated in Italic, became fricatives, not pure aspirates, a character which they only retained in Greek and Sanskrit.
(iii.) Indo-European ŏ.—With Greek and Celtic, Latin preserved the Indo-European ŏ, which in the more northerly groups (Germanic, Balto-Slavonic), and also in Indo-Iranian, and, curiously, in Messapian, was confused with ă. The name for olive-oil, which spread with the use of this commodity from Greek (ἔλαιϝον) to Italic speakers and thence to the north, becoming by regular changes (see below) in Latin first *ólaivom, then *óleivom, and then taken into Gothic and becoming alēv, leaving its parent form to change further (not later than 100 B.C.) in Latin to oleum, is a particularly important example, because (a) of the chronological limits which are implied, however roughly, in the process just described, and (b) of the close association in time of the change of o to a with the earlier stages of the “sound-shifting” (of the Indo-European plosives and aspirates) in German; see Kretschmer, Einleit. p. 116, and the authorities he cites.
(iv.) Accentuation.—One marked innovation common to the western groups as compared with what Greek and Sanskrit show to have been an earlier feature of the Indo-European parent speech was the development of a strong expiratory (sometimes called stress) accent upon the first syllable of all words. This appears early in the history of Italic, Celtic, Lettish (probably, and at a still later period) in Germanic, though at a period later than the beginning of the “sound-shifting.” This extinguished the complex system of Indo-European accentuation, which is directly reflected in Sanskrit, and was itself replaced in Latin and Oscan by another system already mentioned, but not in Latin till it had produced marked effects upon the language (e.g. the degradation of the vowels in compounds as in cōnficio from cón-facio, inclūdo from ín-claudo). This curious wave of accentual change (first pointed out by Dieterich, Kuhn’s Zeitschrift, i., and later by Thurneysen, Revue celtique, vi. 312, Rheinisches Museum, xliii. 349) needs and deserves to be more closely investigated from a chronological standpoint. At present it is not clear how far it was a really connected process in all the languages. (See further Kretschmer, op. cit. p. 115, K. Brugmann, Kurze vergleichende Grammatik (1902–1904), p. 57, and their citations, especially Meyer-Lübke, Die Betonung im Gallischen (1901).)
To these larger affinities may be added some important points in which the Italic group shows marked resemblances to other groups.
5. Italic and Celtic.—It is now universally admitted that the Celtic languages stand in a much closer relation than any other group to the Italic. It may even be doubted whether there was any real frontier-line at all between the two groups before the Etruscan invasion of Italy (see Etruria: Language; Liguria). The number of morphological innovations on the Indo-European system which the two groups share, and which are almost if not wholly peculiar to them, is particularly striking. Of these the chief are the following.
(i.) Extension of the abstract-noun stems in -ti- (like Greek φάτις with Attic βάσις, &c.) by an -n- suffix, as in Lat. mentio (stem menti-ōn-) = Ir. (er-)mitiu (stem miti-n-), contrasted with the same word without the n-suffix in Sans. mati-, Lat. mens, Ind.-Eur. *mn̥-ti-. A similar extension (shared also by Gothic) appears in Lat. iuventū-t-, O. Ir. óitiu (stem oiliūt-) beside the simple -tu- in nouns like senātus.
(ii.) Superlative formation in -is-m̥mo- as in Lat. aegerrimus for *aegr-ism̥mos, Gallic Οὐξισάμη the name of a town meaning “the highest.”
(iii.) Genitive singular of the o-stems (second declension) in -ī Lat. agri, O. Ir. (Ogam inscriptions) magi, “of a son.”
(iv.) Passive and deponent formation in -r, Lat. sequitur = Ir. sechedar, “he follows.” The originally active meaning of this curious -r suffix was first pointed out by Zimmer (Kuhn’s Zeitschrift, 1888, xxx. 224), who thus explained the use of the accusative pronouns with these “passive” forms in Celtic; Ir. -m-berar, “I am carried,” literally “folk carry me”; Umb. pir ferar, literally ignem feratur, though as pir is a neuter word ( = Gr. πῦρ) this example was not so convincing. But within a twelvemonth of the appearance of Zimmer’s article, an Oscan inscription (Conway, Camb. Philol. Society’s Proceedings, 1890, p. 16, and Italic Dialects, p. 113) was discovered containing the phrase ůltiumam (iůvilam) sakrafi̊r, “ultimam (imaginem) consecraverint” (or “ultima consecretur”) which demonstrated the nature of the suffix in Italic also. This originally active meaning of the -r form (in the third person singular passive) is the cause of the remarkable fondness for the “impersonal” use of the passive in Latin (e.g., itur in antiquam silvam, instead of eunt), which was naturally extended to all tenses of the passive (ventum est, &c.), so soon as its origin was forgotten. Fuller details of the development will be found in Conway, op. cit. p. 561, and the authorities there cited (very little is added by K. Brugmann, Kurze vergl. Gramm. 1904, p. 596).
(v.) Formation of the perfect passive from the -to- past participle, Lat. monitus (est), &c., Ir. léic-the, “he was left,” ro-léiced, “he has been left.” In Latin the participle maintains its distinct adjectival character; in Irish (J. Strachan, Old Irish Paradigms, 1905, p. 50) it has sunk into a purely verbal form, just as the perfect participles in -us in Umbrian have been absorbed into the future perfect in -ust (entelust, “intenderit”; benust, “venerit”) with its impersonal passive or third plural active -us(s)so (probably standing for -ussor) as in benuso, “ventum erit” (or “venerint”).
To these must be further added some striking peculiarities in phonology.
(vi.) Assimilation of p to a qṷ in a following syllable as in Lat. quinque = Ir. cóic, compared with Sans. pánca, Gr. πέντε, Eng. five, Ind.-Eur. *penqe.
(vii.) Finally—and perhaps this parallelism is the most important of all from the historical standpoint—both Italic and Celtic are divided into two sub-families which differ, and differ in the same way, in their treatment of the Ind.-Eur. velar tenuis q. In both halves of each group it was labialized to some extent; in one half of each group it was labialized so far as to become p. This is the great line of cleavage (i.) between Latinian (Lat. quod, quandō, quinque; Falisc. cuando) and Osco-Umbrian, better called Safine (Osc. pod, Umb. panū- [for *pandō], Osc.-Umb. pompe-, “five,” in Osc. půmperias “nonae,” Umb. pumped̠̣ia-, “fifth day of the month”); and (ii.) between Goidelic (Gaelic) (O. Ir. cóic, “five,” maq, “son”; modern Irish and Scotch Mac as in MacPherson) and Brythonic (Britannic) (Welsh pump, “five,” Ap for map, as in Powel for Ap Howel).
The same distinction appears elsewhere; Germanic belongs, broadly described, to the q-group, and Greek, broadly described, to the p-group. The ethnological bearing of the distinction within Italy is considered in the articles Sabini and Volsci; but the wider questions which the facts suggest have as yet been only scantily discussed; see the references for the “Sequanian” dialect of Gallic (in the inscription of Coligny, whose language preserves q) in the article Celts: Language.
From these primitive affinities we must clearly distinguish the numerous words taken into Latin from the Celts of north Italy within the historic period; for these see especially an interesting study by J. Zwicker, De vocabulis et rebus Gallicis sive Transpadanis apud Vergilium (Leipzig dissertation, 1905).
6. Greek and Italic.—We have seen above (§ 4, i., ii., iii.) certain broad characteristics which the Greek and the Italic groups of language have in common. The old question of the degree of their affinity may be briefly noticed. There are deep-seated differences in morphology, phonology and vocabulary between the two languages—such as (a) the loss of the forms of the ablative in Greek and of the middle voice in Latin; (b) the decay of the fricatives (s, v, i̭) in Greek and the cavalier treatment of the aspirates in Latin; and (c) the almost total discrepancy of the vocabularies of law and religion in the two languages—which altogether forbid the assumption that the two groups can ever have been completely identical after their first dialectic separation from the parent language. On the other hand, in the first early periods of that dialectic development in the Indo-European family, the precursors of Greek and Italic cannot have been separated by any very wide boundary. To this primitive neighbourhood may be referred such peculiarities as (a) the genitive plural feminine ending in -āsōm (Gr. -άων, later in various dialects -έων, -ῶν, -ᾶν; cf. Osc. egmazum “rerum”; Lat. mensarum, with -r- from -s-), (b) the feminine gender of many nouns of the -o- declension, cf. Gr. ἡ ὁδὸς, Lat. haec fāgus; and some important and ancient syntactical features, especially in the uses of the cases (e.g. (c) the genitive of price) of the (d) infinitive and of the (e) participles passive (though in
