A word appearing as ᴱQ. tolpo “bowl” in Early Qenya Word-lists of the 1920s (PE16/142). The Qenya Lexicon and Poetic and Mythological Words of Eldarissa of the 1910s instead had ᴱQ. salpa “bowl” derived the early root ᴱ√SḶPḶ (QL/84).
Neo-Quenya: I would use the later word ᴺQ. tolpo as the Neo-Quenya word for “bowl”, since later ON. salpha from the 1930s was “broth” rather than “bowl” (Ety/SÁLAP).
