A word appearing in its instrumental forms talainen or talalínen “with/on wings” in various versions of the ᴱQ. Oilima Markirya from around 1930 (MC/213, 220). In the earliest drafts of the poem, the form was ᴱQ. alainen “upon wings” (PE16/062). In a glossary associated with one of the drafts, Tolkien translated tala as “sail” (PE16/75), perhaps indicating the translation “wings” was metaphorical.
Early Quenya
velu-
verb. to unroll, unfurl
velu
noun. sail
tala
noun. sail
velunte
noun. sail
A word appearing as a noun ᴱQ. velunte “sail” in the Qenya Lexicon of the 1910s under the early root ᴱ√VELU “unroll” (QL/100). In the contemporaneous Gnomish Lexicon, Tolkien compared G. belon “sail” to Q. velu (GL/22), but that could be a reference to the root.
Neo-Quenya: I would retain ᴺQ. veluntë “sail” for purposes of Neo-Quenya, based on a Neo-Root ᴺ√BELU “unroll”.
A verb appearing as ᴱ√VELU- “unroll” in the Qenya Lexicon, identical in form to its root (QL/100). Under the entry for its antonym ᴱ√TOL+U “roll up, furl”, the verb velu- was glossed “unfurl”.
Neo-Quenya: There is a later verb ᴹQ. panta- “to unfurl, spread out, open” from The Etymologies of the 1930s (Ety/PAT), but that verb seems to mean “✱open up” rather than “unroll”. I would therefore retain ᴺQ. velu- “to unroll, unfurl” for purposes of Neo-Quenya, based on a Neo-Root ᴺ√BELU, to salvage words like [ᴱQ.] velupantië “revelation”.
