Ilk. [esk] became [esg]; [esk] > [esg]
Where an initial [esk-] developed from an initial [sk-], it further developed into [esg-], such as: ᴹ✶skal(a) > [eskal >] Ilk. esgal (Ety/SKAL¹) or ᴹ✶skar > [eskar >] Ilk. esgar¹ (Ety/SKAR). The same development occurred from initial [esk-] produced by the Ilkorin syncope: ᴹ✶eseke > [esk(e) >] Ilk. esg¹ (Ety/ESEK).
The combination [sk] only developed into [sg] after [e]. It remained for other vowels, such as: ᴹ✶us(u)kwē > Ilk. usc (Ety/USUK) or ᴹ✶askarā > Ilk. ascar (Ety/SKAR). It is unclear whether or not this development occurred for non-initial [esk], however.
