A noun appearing as G. mechor “gore” in the Gnomish Lexicon of the 1910s (GL/56), clearly related to the early root ᴱ√MEHE “ooze‽” from the contemporaneous Qenya Lexicon that was likewise the basis for “gore” words (QL/60).

Neo-Sindarin: I would retain this word as ᴺS. mechor “gore” for purposes of Neo-Sindarin, derived from a Neo-Root ᴺ√MEKH of similar meaning, from primitive *mekhār or *mekhrē.
