savarna

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.
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.
ᴱQ. savarda or savarna “pack of dogs, wolves” appeared in the Qenya Lexicon of the 1910s as an elaboration of ᴱQ. savar “wild dog, jackal” under the early root ᴱ√SAẆA (QL/82).
Neo-Quenya: For purposes of Neo-Quenya, I’d update this word to ᴺQ. huarda “pack (of dogs, wolves)” using the later root ᴹ√KHUG that seems to have replaced ᴱ√SAẆA (Ety/KHUGAN).
