The verb ᴱQ. tuvu- appeared in the Qenya Lexicon of the 1910s glossed “receive, accept, take, require, cost” under the early root ᴱ√TUVU (QL/96). It also appeared in the contemporaneous Gnomish Lexicon with the gloss “receive”, given as the cognate of G. tû- “receive; take; get; become” (GL/71). The verb appeared in the 1920s Early Qenya Grammar as tuv “receive, take”, with past túvie and present tuve or tue, along with an “impersonal” variant tú (PE14/58).

Similar verb forms ᴹQ. tuvo “take” and túvie “took” appeared in the first version of Quenya Personal Pronouns (QPP1) the late 1940s (PE23/92). The aorist verb form tuvo is peculiar, but it may be in that moment Tolkien imagined this was a u-verb tuvu-, and that the aorist forms of such a u-verb was tuvo < *tuvŭ rather than tuvu < *tuvū as it was in other documents of this period such as the Quenya Verbal System (QVS), also from 1948 (PE22/114).

QVS also introduced a new meaning for ᴹQ. tuve “finds” (PE22/108 note #50) in that document revised to ᴹQ. kime (PE22/108, 125), but later still Q. utúvienyes “I have found it” appeared in The Lord of the Rings. See those entries for further discussion.

Neo-Quenya: It is possible that tuvu- “receive, take” was displaced by Q. tuv- “find, discover”. However, we have no good Quenya word for “take”, so I for purposes of Neo-Quenya I would retain tuvu- “take” as a u-verb, perhaps related somehow to tuv- “find” after considerable semantic drift. I would also retain the early meanings “require, cost”, as in tuvus miriani canta “it costs four mirian [a Gondorian coins]”. For “receive, accept”, I would instead use the later verb cav-.
