The noun N. oegas “mountain peak” appeared in The Etymologies as a noun form of oeg “sharp, pointed, piercing” (Ety/AYAK). In Noldorin, often ancient ai became oe, whereas in Sindarin ai fairly consistently became ae. Thus if adapting this word to Sindarin, its form would likely be ᴺS. aegas, as suggested in Hiswelókë’s Sindarin Dictionary (HSD/aegas).
