There are more words but they are from Tolkien's earlier conceptional periods. Tolkien likely changed these words as he evolved the aesthetics and completeness of the languages. You may even find languages that Tolkien later rejected. Do not mix words from different time periods unless you are familiar with the phonetic developments.

Qenya 

tap-

verb. to stop, block

Qenya [Ety/TAP; EtyAC/TAP] Group: Eldamo. Published by

tam-

verb. to tap

A verb in The Etymologies of the 1930s appearing as tamin “I tap” under the root ᴹ√TAM “knock” (Ety/TAM). See the entry ᴹQ. ton- for other similar “tap, knock” verbs.

ton-

verb. to tap, knock

A verb in the Quenya Verbal System (QVS) of 1948 derived from the root ᴹ√TON “tap, knock” and so presumably with the same meaning (PE22/103). It replaced a verb tun- from a deleted root ᴹ√TUN “tap, knock, touch (with the fingers)” (PE22/103).

Conceptual Development: A possible precursor ᴱQ. otto- “knock” appeared in the Qenya Lexicon of the 1910s under the early root ᴱ√OTO of the same meaning (QL/71). This in turn may have become ᴹQ. tam- “to tap” and ᴹQ. tamba- “to knock, keep on knocking” from The Etymologies of the 1930s under the root ᴹ√TAM “knock” (Ety/TAM). Finally there are some roots √TOK and √NOK from 1959-60 notes used of “non-resonant sounds” but with no derivatives (PE17/138).

Neo-Quenya: For purposes of Neo-Quenya, I would use the later attested verbs, but I would assume tam- is for a lighter “tap” vs. ton- for a deeper (single) “knock”, whereas tamba- is for repeated knocking or tapping.

vanta-

verb. to walk, to walk, *trudge, trek

A verb for “to walk” in The Etymologies of the 1930s under the root ᴹ√BAT “tread” (Ety/BAT).

Neo-Quenya: For purposes of Neo-Eldarin, I assume ᴹ√BAT is for a “heavy walk” as opposed for √PAT for a “light walk” or “step”, so I would use vanta- for an extended or serious walk, and thus including “✱trudge” and “✱trek”.
