A noun in the Qenya Lexicon of the 1910s given as ᴱQ. tampo “a well”, derived from the root ᴱ√TṂPṂ “build”; Tolkien considered transferring the word to ᴱ√TAPA “✱stretch” (QL/93). This word also appeared in the Poetic and Mythological Words of Eldarissa (PME/93).
Neo-Quenya: I think ᴺQ. tampo “well” might be salvaged in Neo-Quenya as a derivative of √TAM “construct”; it is used this way in Helge Fauskanger’s NQNT (NQNT).
A noun in the Qenya Lexicon of the 1910s under the early root ᴱ√MAẎA, with the gloss “horse” in parenthesis marked with a “?”, followed by the gloss “mane, flowing hair” (QL/60).
