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.
tal
adverb. downwards
tál
noun. foot; bottom
tallune
noun. sole of foot
talat
noun. sheet
A word for “sheet” in the Declension of Nouns (DN) from the early 1930s of unclear derivation.
Conceptual Development: In Early Qenya Word-lists of the 1920s, ᴱQ. talat was “dry land” (PE16/139). The word talat also appeared (unglossed) in notes on The Feanorian Alphabet from the mid-to-late 1930s (PE22/20).
tal(de)
adverb. so, thus, like that
Below: Tolkien's Late Period (1950–1973). These are from Tolkien's late conceptual period — his most settled forms of the languages. Prefer these over the earlier ones above when composing new text.
A noun in The Etymologies of the 1930s glossed “sole of foot”, a combination of ᴹQ. tál “foot” and the root ᴹ√RUN “flat of hand or sole of foot” (Ety/RUN). Tolkien gave a primitive form ᴹ✶talrunya after this word, but that is unlikely to produce the Quenya word tallune; a second primitive element of ✱-runē is more likely.
Conceptual Development: The Qenya Lexicon of the 1910s has the word ᴱQ. talas (talast-) “sole” under the early root ᴱ√TALA “support”, also the basis for ᴱQ. tala “foot” (QL/88). The contemporaneous Poetic and Mythological Words of Eldarissa gave it only in its stem form talast- “sole” (PME/88).
