A noun appearing as ᴱQ. hyar (hyarm-) “a plough” in the Qenya Lexicon of the 1910s under the early root ᴱ√HYAŘA [HYAÐA] “plough through” (QL/41). In the contemporaneous Poetic and Mythological Words of Eldarissa it appeared only as its stem form hyarm- “plough” (PME/41). Early Qenya Word-lists of the 1920s had ᴱQ. hyarma “a plough” (PE16/144).

Neo-Quenya: The form hyarma conflict with the later word Q. hyarma “left hand”. However, since the later root ᴹ√SYAD had a similar meaning “shear through, cleave” in The Etymologies of the 1930s (Ety/SYAD), I think ᴺQ. hyar “plough” can be salvaged for purposes of Neo-Quenya derived from a primitive form like *syadĕ.
