The Quenya verb for “to come”, which is very well-attested. It is derived from the root √TUL whose basic sense is “move towards the speaker” (PE17/188), as in “come here”: á tule sís. English may also use “come with” in the sense “accompany” such as “I will come with you”, but Quenya uses men- (“go”) for this purpose (PE22/162), such as menuvan ó le = “I will go with you”.
Conceptual Development: ᴱQ. tulu- dates all the way back to the Qenya Lexicon of the 1910s, where it appeared under the early root ᴱ√TULU, but in that early document it has a much broader set of glosses: “(1) bring, carry, fetch; (2) intr. move, come; (3) produce, bear fruit” (QL/95). By the Early Qenya Grammar of the 1920s its list of glosses was reduced to “come” (PE14/57), and Tolkien used the verb only to mean “come” thereafter. Tolkien often used this verb in grammatical examples, which is part of the reason it is so well-attested.
The root √TUL was used for Elvish words having to do with motion towards a speaker for much of Tolkien’s life, but the precise meaning evolved over time. The earliest appearance of this root was as ᴱ√TULU “fetch, bear, bring; move, come”, but with an original sense = “uphold, support, bear, carry” (QL/95). It had a derived verb ᴱQ. tulu- matching the verbal sense of the root along with an added sense “produce, bear fruit”, but it had other derivatives like ᴱQ. tulma “bier, tray” and ᴱQ. tulwe “tall thin pillar, standard, pole; banner” connected to the older “support” sense of the root. It had a similar divergence of meaning in its derivatives from the contemporaneous Gnomish Lexicon, such as G. taul “a pillar” vs. G. tul- “bring; come to” (GL/69, 71). This 1910s root ᴱ√TULU may also have been connected to ᴱ√TḶPḶ which likewise had derivatives having to do with “support” (QL/93).
In The Etymologies of the 1930s the root ᴹ√TUL had the gloss “come, approach, move towards (point of speaker)” with derivatives like ᴹQ. tul-/N. tol- “come” and ᴹQ. tulta-/N. toltha- “send for, fetch, summon” = “(orig.) make come” (Ety/TUL); in the 1930s the “support” words seem to have been transferred to (probably unrelated) ᴹ√TULUK. √TUL “come” was mentioned regularly in Tolkien’s later writings (PE22/103; PE17/188; PE22/156), in one 1969 note with the extra gloss “approach” (PE22/168), so the 1930s senses for the root seem to have been retained thereafter.
