Below: Tolkien's Late Period (1950–1973). These are from Tolkien's late conceptual period — his most settled forms of the languages. Prefer these over the earlier ones above when composing new text.
A verb appearing as ᴱQ. nó- “be born” in the Qenya Lexicon of the 1910s under the early root ᴱ√NŌ “become, be born”, with an unusual past[?] form nōte (QL/66). Somewhat later Tolkien added the gloss “become” to the verb nó- as well.
