“…Many phonological (or partially phonological) accounts of the initial mutations of Irish and the other Celtic languages have been proposed, grounded in a number of theoretical frameworks and spanning several decades, including Hamp (1951), Rogers (1972), Lieber (1983, Ní Chiosáin (1991), Swingle (1993), Grijzenhout (1995), Pyatt (1997), and Wolf (2007). Another longstanding and growing body of scholarship argues that the initial mutations belong, at least in part, to the morphology or the lexicon, including Hamp (1951), Oftedal (1962), Green (2003Green ( , 2006Green ( , 2007, Stewart (2004), Mittendorf and Sadler (2006), Iosad (2008Iosad ( , 2010Iosad ( , 2014, Hannahs (2013). For details of these models, the reader is referred to the original sources, as well as to the summaries and discussions in Stewart (2004) and Hannahs (2011).…”
