Common Celtic
The reconstruction of Common Celtic (or Proto-Celtic)—the parent language that yielded the various tongues of Continental Celtic and Insular Celtic—is of necessity very tentative. Whereas Continental Celtic offers plenty of evidence for phonology (the sound system), its records are too scanty to help much with the grammar (morphology or syntax), for which the best available evidence is Old Irish, the most archaic of the Insular languages. The records provide a picture of a language of the same type as Latin or Common Germanic; that is, one that still maintains a considerable part of the structure of the ancestral Indo-European language and has not lost final or medial syllables. Its vowel system differs only slightly from that reconstructed for Indo-European by the French linguist Antoine Meillet. Differences include the occurrence of Celtic *ī for Indo-European *ē (e.g., Gaulish rix and Irish rí, “king”; compare Latin rex) and *ā in place of *ō. (An asterisk [*] before a letter or word indicates that the sound or word is not attested but is a hypothetical, reconstructed form.)

The consonantal system, too, is conservative, although there are some striking features. Among them are the loss of *p (e.g., Irish athair “father”; cf. Latin pater) and the falling together of the aspirated and unaspirated voiced stops assumed for Indo-European. (A stop is a consonant made with complete momentary stoppage of the breath stream some place in the vocal tract; voiced stops are those produced with the vocal cords vibrating, such as b, d, g. An aspirated sound is accompanied by a puff of breath, often written as an h, as in bh, dh, gh; an unaspirated consonant lacks this accompanying puff of breath.) Thus, Old Irish dán “what is given” corresponds to Latin donum “gift” (from Indo-European *d), but Old Irish de-naid “sucks” corresponds to Latin fe- in fe-mina, fe-llare (from Indo-European *dh). This loss of distinctive aspiration occurs with three out of the four voiced stops, a situation close to that of Slavic.
Other considerations, however, show that Celtic belongs to the so-called southern group of the European branch of Indo-European languages, or in another classification, to the same centum group as Latin, whereas Slavic belongs to the satem group. (The centum and satem divisions of Indo-European languages are made according to the treatment of certain sounds, called palatals, that existed in the ancestral Indo-European language.)
The loss of *p in Celtic was very early; only the place-name Hercynia, preserved in Greek, shows that, in initial position, it became an h sound before disappearing. In most of the known Celtic languages, a new p sound has arisen as a reflex of the Indo-European *kw sound. Thus there is Gaulish pempe, Welsh pimp “five,” compared to Old Irish cóic and Latin quinque “five.” The Irish evidence shows that *kwenkwe must be reconstructed as the form in Common Celtic. The terms P-Celtic and Q-Celtic are sometimes used to describe assumed divisions of Common Celtic; to use one sound shift to distinguish dialects is, however, hardly justified, and the classification will not be used in this article.
The morphology (structure) of nouns and adjectives shows no striking changes from Indo-European. The Irish verb, however, exhibits a remarkable archaism not found in any other recorded Indo-European language. It has recently been demonstrated that the so-called primary and secondary endings of the Indo-European verb, as in the 3rd person singular endings *-(e)t and -(e)ti, both occurred in the same tense. The forms with *-i were used when the verb had absolute initial position; those without it were used in the normal verbal position at the end of the sentence. This is reflected in the Old Irish forms beirith (from *bereti) “he bears” and ní beir (from *beret) “he does not bear.” It cannot be stated with certainty that Continental Celtic had preserved such forms. The Continental Celtic dialects show a few cases of sentences—admittedly imperfectly understood—in which the verb appears to be placed after the subject and before the object, as in modern western European languages. The history of Insular Celtic, however, shows a gradual shift from the older final position of the verb to the initial position, a position that has now become regular in all of the languages.
