S. erin prep. “on the ... day” (Category: Up, Above, Over)
A word in the King’s Letter appearing in the phrases erin dolothen Ethuil “on the eighth day of Spring” and erin Gwirith edwen “[on] the second day of April”. Carl Hostetter suggested (VT31/26) that this form is some derivative of the root ᴹ√AR¹ “day” while David Salo suggested it is a prepositional form combining [N.] or “above” with the definite article, perhaps with the sense “[up]on the”. Of the two, I thing Salo’s definite-preposition explanation is a bit more likely.
