A word for “measure” in ᴹQ. Fíriel’s Song from the 1930s, appearing only in its instrumental form lestanen “in measure” (LR/72).

Conceptual Development: The Qenya Lexicon of the 1910s had ᴱQ. talma “a weight, measure” under the early root ᴱ√TALA “support” (QL/88), a word also appearing in the contemporaneous Poetic and Mythological Words of Eldarissa with the gloss “weight” (PME/88).
