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.

skal

root. small fish

A root in The Etymologies of the 1930s glossed “small fish” with derivatives like ᴹQ. hala of the same meaning and ᴹQ. halatir(no)/N. heledir “kingsfisher, (lit.) fish-watcher” (Ety/SKAL²). Elsewhere in The Etymologies Tolkien had ᴹ√KHAL¹ “(small) fish” (Ety/KHAL¹), but there the root was revised to ᴹ√KHOL before the entry was deleted with reference to ᴹ√SKAL (Ety/KHAL¹). TThis primitive khal-form for “fish” also appeared as a note on the title page of The Etymologies (EtyAC/KHAL¹).
