SGDS shows strong preaspiration in this area as Diack shows in his pronunciation. It also shows no velarisation in final -nn. That is to say, aXtun represents the local pronunciation of Aitionn. Watson's form may be a slight etymologisation although it is supported by the modern form and Pont's form.
