Hypothesis of non-Indo-European languages
Ireland was settled, like the rest of northern Europe, after the retreat of the ice sheets c. 10,500 BC. Indo-European languages are usually thought to have been a much later arrival.
Scholars have suggested that:
Suggested non-Indo-European words in Irish
Gearóid Mac Eoin proposes the following words as deriving from the substrate: bréife 'ring, loop', cufar, cuifre/cuipre 'kindness', fafall/fubhal, lufe 'feminine', slife, strophais 'straw'; and the following placenames: Bréifne, Crufait, Dún Gaifi, Faffand, Grafand, Grafrenn, Life/Mag Liphi, Máfat.
Peter Schrijver submits the following words as deriving from the substrate: partán 'crab', Partraige (ethnonym), (note that partaing "crimson (Parthian) red" is a loanword from Lat. parthicus), pattu 'hare', petta 'pet, lap-dog', pell 'horse', pít 'portion of food', pluc '(round) mass', prapp 'rapid', gliomach 'lobster', faochán 'periwinkle', ciotóg 'left hand', bradán 'salmon', scadán 'herring'. In a further study he gives counter-arguments against some criticisms by Graham Isaac.
Ranko Matasović points out that there are words of possibly or probably non-Indo-European origin in other Celtic languages as well; therefore, the substrate may not have been in contact with Primitive Irish but rather with Proto-Celtic. Examples of words found in more than one branch of Celtic but with no obvious cognates outside Celtic include:
