Primitive Irish

Primitive Irish or Archaic Irish (Irish: Gaeilge Ársa, Gaeilge Chianach), also called Proto-Goidelic, is the oldest known form of the Goidelic languages, and the ancestor of all languages within this family.

This phase of the language is known only from fragments, mostly personal names, inscribed on stone in the Ogham alphabet in Ireland and western Great Britain between the 4th and the 6th century AD, before the advent of Old Irish. These inscriptions are referred to as Orthodox Ogham, although scholastic use of the script continued residually until the early 19th century.

Primitive Irish is the oldest recorded form of the Goidelic languages. It was written in the Ogham alphabet, the usage of which can be divided into two phases, Orthodox Ogham and Scholastic Ogham.

The former represents the earlier tradition of inscriptions recording an individual's name, optionally with parentage, perhaps as a memorial or indicator of land ownership, whereas the latter resulted from a tradition of scholarly restoration of the writing system as part of the development of a Celtic style of Catholic art, in parallel with the use of the Latin alphabet in ordinary writing. Primitive Irish is known only from Ogham fragments, usually personal names, the earliest being dated by academics to the 4th century, although some estimates for the earliest inscriptions range between the 1st and 5th centuries. Scholars agree that the orthodox written tradition is older than the surviving inscriptions. The latest inscriptions of the orthodox tradition appear to come from the 6th century. The scholastic use of Ogham continued until the early 19th century, the last inscription being found on the tomb of Mary Dempsey at Ahenny in County Tipperary, which is written in both Irish and English.

Transcribed Ogham inscriptions, which lack a letter for /p/, show Primitive Irish to be similar in morphology and inflections to Gaulish, Latin, Classical Greek and Sanskrit. Many of the characteristics of modern (and medieval) Irish, such as initial mutations, distinct "broad" and "slender" consonants and consonant clusters, are not yet apparent.

More than 300 Ogham inscriptions are known in Ireland, including 121 in County Kerry and 81 in County Cork, and more than 75 found outside Ireland in western Britain and the Isle of Man, including more than 40 in Wales, where Irish colonists settled in the 3rd century, and about 30 in Scotland, although some of these are in Pictish. Many of the British inscriptions are bilingual in Irish and Latin; however, none show any sign of the influence of Christianity or Christian epigraphic tradition, suggesting they date from before 391, when Christianity became the official religion of the Roman Empire. Only about a dozen of the Irish inscriptions show any such sign. There is speculation about the orthodoxy of one inscription in Hampshire and two in Scotland, but there is no academic consensus on the matter.

The majority of ogham inscriptions are memorials, consisting of the name of the deceased in the genitive case, followed by MAQI, MAQQI, "[the stone] of the son" (Modern Irish mic), and the name of his father, or AVI, AVVI, "[the stone] of the grandson", (Modern Irish uí) and the name of his grandfather, e.g. DALAGNI MAQI DALI, "[the stone] of Dalagnos son of Dalos". Sometimes the phrase MAQQI MUCOI, "of the son of the tribe", is used to show tribal affiliation. Inscriptions demonstrating additional information are rare, such as QRIMTIR RON[A]NN MAQ COMOGANN, "[the stone] of the priest Ronán son of Comgán". Some inscriptions appear to be border markers.

The brevity of most orthodox ogham inscriptions makes it difficult to analyse the archaic Irish language in depth, but it is possible to understand the basis of its phonology and the rudiments of its nominal morphology.
