In the Qenya Lexicon of the 1910s, ᴱQ. Ion was the “mystic name of God, 2nd Person of Blessed Trinity”, that is the “Son” in the “Father, Son, Holy Ghost” trinity (QL/43). In that document yon or yond- was given in a couple of places as (archaic?) words for “son” (QL/43, 106). In Early Noldorin Word-lists of the 1920s, Tolkien gave ion as the equivalent of ᴱN. gó “son”, along with a plural form yondi (PE13/113). However, in the English-Qenya Dictionary Tolkien said yondi was an irregular plural form of ᴱQ. yondo “son” (PE15/77), and this is the form he typically used in later writings.

A word for “woman” in Early Qenya Word-lists of the 1920s with stem form nyel-, as indicated by its accusative nyela (PE16/135). Its etymology is unclear; Patrick Wynne and Christopher Gilson suggested it might be connected to the early root ᴱ√NYEHE “weep” or later root ᴹ√NYEL “ring, sing”, but these both feel like stretches to me.
nî
noun. woman
salpa
noun. bowl
tolpo
noun. bowl
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).
