Cóemgen (Old Irish)

Where does "Cóemgen" come from?

The Old Irish male given name 'Cóemgen' is a compound word formed from 'cóem', meaning 'dear, beloved, beautiful', and 'gein', meaning 'birth' or 'person'[1]. The element 'cóem' descends from Proto-Celtic '*koimos', meaning 'dear, nice', which ultimately traces back to the Proto-Indo-European root '*ḱey-' meaning 'to settle'[3][5][6]. Meanwhile, the element 'gein' derives from Proto-Celtic '*genan', tracing back to the Proto-Indo-European root '*ǵenh₁-'[2].

Open questions

The Proto-Indo-European root 'ḱey-' may have shifted in meaning from 'to settle' to include 'to be lying down' or 'to fall' based on evidence in Celtic and Sanskrit. [4] [6]
