ómun

• omun, homun (with short vowel)

From Proto-Celtic *oβnus. The ó is unexpected, since fricative-induced compensatory lengthening did not occur, as no fricative was deleted. Thurneysen explained the long ó as being transferred from the synonym úath (“fear”) before that word underwent diphthongization.^[1] Forms with the expected short vowel like omun are also attested and are completely interchangeable with the long-vowel forms, even within a single Old Irish speaker's writings.
