Nuclear Celtic languages


The Nuclear Celtic languages, also known as Gallo-Insular Celtic, Gallo-Brythonic–Goidelic, and, ambiguously in terms of the position of Lepontic, North Celtic or Core Celtic, are a group of Celtic languages once spoken across Europe and the British Isles, reaching even Anatolia, but nowadays restricted to the Celtic nations. It consists of all Celtic languages that are not Hispano-Celtic, namely the Insular Celtic languages together with the extinct Gaulish and Lepontic languages.
The Nuclear Celtic languages separated from Hispano-Celtic around 900 BC, possibly due to Phoenician influence causing Hispano-Celtic to drift away from a common Celtic cultural sphere.

Terminology and internal classification

The terms used to refer to the Celtic grouping comprising Gaulish, Goidelic and Brittonic, and also the position of Lepontic in this grouping, vary by author.

"Nuclear Celtic" and "Core Celtic"

Eska defines Nuclear Celtic as including Gaulish, Lepontic, and the Insular Celtic languages, and furthermore defines Core Celtic as a sub-branch of Nuclear Celtic that excludes Lepontic. On the other hand, Stifter redefines Core Celtic to include Lepontic, making it synonymous to what Eska terms Nuclear Celtic.
Eska's internal taxonomy of Nuclear Celtic is as follows:
  • Nuclear Celtic
  • *Cisalpine Celtic: Lepontic → Cisalpine Gaulish
  • * Core Celtic
  • ** "similar to Transalpine Celtic"
  • ***Transalpine Gaulish
  • ***Galatian
  • ***Noric
  • **Insular Celtic
  • ***Goidelic
  • ***Brittonic

    "North Celtic"

Schrijver defines North Celtic as referring to what Eska calls Core Celtic, namely a grouping of Gaulish and Insular Celtic to the exclusion of Lepontic. He also groups Hispano-Celtic and Lepontic together in a contrasting grouping he calls South Celtic. Schrijver's Celtic taxonomy is as follows:
However, Jørgensen, despite borrowing Schrijver's North Celtic and South Celtic terminology, redefines North Celtic to include Lepontic as well. This redefined North Celtic is thus identical to Eska's Nuclear Celtic. Jørgensen's redefinition of North Celtic is as follows:
  • North Celtic
  • * Lepontic
  • *
  • ** Gaulish
  • **Goidelic
  • **Brittonic

    Other terms

Gallo-Insular Celtic and Gallo-Brythonic–Goidelic are terms coined, respectively, by Kim McCone and John T. Koch. Gallo-Insular Celtic's family tree is defined by McCone as follows:
  • Gallo-Insular Celtic
  • * Gaulish
  • * Insular Celtic
  • ** Goidelic
  • ** Brittonic

    Common characteristics

Common characteristics of the Nuclear Celtic branch include:
  • *st becoming a phoneme known as tau gallicum, which was notated variously in Gaulish but merged with -ss- in Goidelic. In contrast, Hispano-Celtic preserved *st as is.
  • Complete monophthongization of the diphthong *ei to in non-final position.
  • Refashioning of the inflected relative pronoun *yos into an uninflected relative particle *yo.
  • Spread of the o-stem genitive singular *-ī, completely absent in Hispano-Celtic.
  • A genitive plural *-om, contrasting with its Hispano-Celtic counterpart -um. Eska believes that *-om is a shared innovation of Nuclear Celtic with Hispano-Celtic preserving an older ending. However, Prósper believes the reverse was the case, with Hispano-Celtic innovating -um ; -om elsewhere would be a retention.
  • The repurposing of *to, originally a connecting particle, into a preverb *to-; such a preverb appears in Cisalpine Gaulish and Insular Celtic.
  • The rise of a characteristic verb complex, including the ability to affix multiple preverbs to a verb simultaneously; both Gaulish and early Insular Celtic allow double prefixation of verbs.
