#ᴱ√SEKE root. “mid”
A root form indicated in the Gnomish Lexicon of the 1910s by an element in primitive ᴱ✶sek’·ðana “midday” > G. saidhon “noon” (GL/66), with further derivatives like G. seg “point, middle point” and G. sectha- “aim at” given later in the document (GL/67). It might be a variant of ᴱ√MEKE the contemporaneous Qenya Lexicon of similar meaning (QL/60). There are no signs of this root in Tolkien’s later writing.
