kirisse

noun. slash, gash

A noun for a “slash, gash” in The Etymologies of the 1930s under the root ᴹ√KIRIS “cut” (Ety/KIRIS).

Conceptual Development: The same form kirisse appeared under the root ᴹ√KIR with the gloss “cleft, (?crevasse)” [the second gloss is unclear], but this form was deleted (EtyAC/KIR). The Qenya Lexicon of the 1910s had a couple similar forms ᴱQ. kiris (kirist-) “cleft, crack” and ᴱQ. kirkis of the same meaning, both under the early root ᴱ√KIŘI [KIÐI] and ᴱ√KISI, along with blended ᴱ√KIRISI, all of these roots having the sense “cut, split” (QL/47).
