In The Etymologies of the 1930s, the verb ᴹQ. yul- “smoulder” was mentioned in passing in a deleted entry for the root ᴹ√GUL (Ety/GUL). Since the root ᴹ√YUL “smoulder” remained undeleted in The Etymologies, perhaps this verb also remained valid in the 1930s (Ety/YUL). However, the later meaning of the verb Q. yul- was “drink” from the root √YUL of the same meaning (PE17/63).

Neo-Quenya: For purposes of Neo-Eldarin, I would adapt the root ᴹ√YUL “smoulder” as the Neo-Root ᴺ√YOL, and hence would adapt this 1930s verb as ᴺQ. yol- “smoulder” to sidestep the conflict with Q. yul- “drink”; see the entry on ᴺ√YOL/YUL for further discussion.
