Ilk. gwilwering n. “butterfly” (Category: Insect)
A noun for “butterfly” derived from the root ᴹ√WIL (Ety/GWEN). Its Quenya cognate ᴹQ. wilwarind- suggests its primitive form was *✶wilwarinde. If so, it is an example of how [nd] sometimes became [ŋg] in Ilkorin. As suggested by Helge Fauskanger, this may be due to assimilation to the preceding [g] (AL-Ilkorin/gwilwering).
