Greek (σ)τεγος “roof”, Old Irish teg, Clare Irish [tʹe’] “house”: a stratified reappraisal of “house” in pan-Gaelic

This article looks at Common Celtic *tegos ‘house’ (cognate with Ancient Greek (s)tegos ‘roof’) in Continental and Insular Celtic sources over a span of some two millennia. It is discovered that the only modern Celtic-speaking areas to preserve the Old Irish nominative singular teg ‘house’ were the dialects of Clare and Tipperary - where teh survived (a form yet to be identified until these findings were published).
The survival of multiple by-forms such as teagh, teach,tigh, toigh ‘house’ in the medieval bardic Irish Grammtical Tracts show the uniqueness of this body of grammatical material in a European context, as it catered for the dialectal rather than insisting on a centralised form.
