§ 278. Medial rʹ+ ʃ gives rs, e.g. fɔrsuw, ‘to harrow’, Di. foirseadh; ïrsαχə, plur. of irʹiʃ, ‘hanger on creel’, Di. iris; kʹɛ꞉rsαχ, ‘hen blackbird’, Meyer céirsech; ʃkʹu꞉rsi꞉, ‘scourges’, Keat. sgiuirse; tïrsαχ, ‘tired’, O.Ir. toirsech; tɔrsαχ, ‘threshold’, M.Ir. tairsech. For sandhi instances see § 461.
In the groups rʹ + ʃ + tʹ, rʹ + ʃ + Nʹ the rʹ is depalatalised, whilst the first part of the ʃ is a retracted alveolar s and the second ʃ. Examples—fαrsNʹə, compar. of fαrsiNʹ, ‘abundant’, fαrsNʹu꞉lʹ, fαrsNʹαχ, ‘abundance’; fɔ꞉rstʹə, ‘harrowed’; fɔ꞉rstʹən, ‘to suit’, fɔ꞉rstʹənʹαχ, ‘suitable’, Di. fóirstineach; kʹlʹi ·ɔrstʹə, ‘harrow’, Di. cliath fuirste.
rʹ has been further depalatalised in ə Nαrəkyʃ, ‘to meet’, Meyer airchess.
§ 279. A voiceless r with strongly breathed off-glide is a very frequent sound in Donegal. It arises from (a) r + fh in futures, e.g. bʹα꞉r̥ə mʹə, ‘I shall shear, clip’; gʹα꞉r̥ə mʹə, ‘I shall cut’; iər̥ə mʹə, ‘I shall ask’. Similarly in kɔ꞉r̥ə, ‘chest’, < cófra (§ 180).

Similarly in past participles, e.g. bw⅄꞉r̥ə, ‘troubled’, O.Ir. búadartha; tuər̥ə, ‘bleached’, Di. tuaraim.
