Quenya
sohta-
verb. to give to drink, drench
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!
Early Quenya
sokto-
verb. to give to drink, drench
A verb appearing as ᴱQ. {sokta-} >> sokto- “give to drink, drench” in the Qenya Lexicon of the 1910s under the early root ᴱ√SOKO with derivatives having to do with “drink” (QL/85).
Neo-Quenya: Since √SOK reappears in Tolkien’s later writing (PE18/94), I think this word can be adapted as ᴺQ. sohta- for purposes of Neo-Quenya.
