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.
kalpa
noun. water-vessel, bucket
kalpa-
verb. to draw water, scoop out, bale out
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 late 1930s glossed “water-vessel” under the root ᴹ√KALPA of the same meaning (Ety/KALPA). The word ᴱQ. kalpa “bucket, vessel” also appeared in the Qenya Lexicon of the 1910s under the early root ᴱ√KḶPḶ “hold, contains (esp. of liquids)” where Tolkien also considered and rejected another form kalpe (QL/47). The word appeared again in the Declension of Nouns of the early 1930s with the gloss “bucket” (PE21/8).
