Beware, older languages below! The languages below were invented during Tolkien's earlier period and should be used with caution. Remember to never, ever mix words from different languages!
tala-
verb. to carry, bring; to weigh (intr.)
tala
noun. foot; bottom, lowest part
tala
noun. sail
tala(no)ite
adjective. footed
An adjective appearing as talaite or talanoite “footed” in the Qenya Lexicon, an elaboration of ᴱQ. tala “foot” (QL/88).
Neo-Quenya: Since -itë remains an adjective suffix in Tolkien’s later conception of the language, I think ᴺQ. talaitë “footed” can be retained for purposes of Neo-Quenya, analogous to Q. maitë “handed”.
tál
noun. foot; bottom, lowest part
velu
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”.
yulu-
verb. to carry
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.
