Q. anca n. “jaws” (Category: Jaw)
A noun for “jaws” appearing in The Lord of the Rings Appendix E as the name for tengwar #15 (f). ᴹQ. anka was first introduced in The Etymologies of the 1930s with the glosses “jaw, row of teeth” and derived from primitive ᴹ✶ankā under the root ᴹ√(A)NAK “bite” (Ety/ÁNAK, NAK).
Conceptual Development: In tengwar charts and other earlier documents from the 1930s up through the early 1950s, anca was in competition with an earlier word anta “jaw” < ✶amtā (earlier ᴱ✶ṃtā) based on the root √MAT “eat” (PE22/22, 51; PE18/85 note #72), but Tolkien ultimately settled on anca. Another early word that might be a precursor to anca is ᴱQ. kâ, cognate to G. gag “jaw” from the Gnomish Lexicon of the 1910s (GL/37).
