√AKAS root. “neck, ridge”
A root for “neck, ridge” coined in the late 1960s, referring both to the biological neck as well as a “neck” or ridge of rocks (PE17/92). In the context where it appeared, it mainly explains the Sindarin name for “Tarlang’s Neck”, Achad Tarlang. It might be related to the 1930s root ᴹ√AK “narrow” (Ety/AK) and might also be the basis for Q. axo “bone” (MC/223), perhaps derived from *ak(a)sō.
