Beware, older languages below! The languages below were invented during Tolkien's earlier period and should be used with caution. Remember to never, ever mix words from different languages!
A noun appearing as ᴱQ. saune in the Qenya Lexicon and Poetic and Mythological Words of Eldarissa of the 1910s glossed “a bath” or “bath, small pool”, and derived from the early root ᴱ√SOVO or ᴱ√SOW̯O “wash” (QL/86; PME/86). Very likely the ancient ou became au as was the usual phonetic development in Qenya of the 1910s and 20s.
Neo-Quenya: I retain ᴺ√SOW “wash” for purposes of Neo-Quenya, so I would adapt this word as ᴺQ. súnë “bath, small pool” using the later Quenya sound change of ou to ū.
