First son of Q. Ingwë in some 1959 notes (NM/128). Elsewhere the son of Ingwë was named Ingwion.
Conceptual Development: The basic development of this name was: ᴱQ. Isilmo (as son of ᴱQ. Isil, QL/43) >> ᴱQ. Ingil (LT1/022, Ety/ING) >> ᴹQ. Ingwiel (SM/156, LR/326) >> Q. Ingwion (WJ/246) >> Q. Ingwil (NM/128). The meanings of earlier forms of this character’s name are unclear, but they all contain his father’s name as an element. See the entries for the earlier name for more details.
A name for the People of Ingwë, the first tribe of Elves, more commonly known as the Vanyar (PM/332, PE17/154-5). It is simply the plural form of the name for their leader: Ingwë.
Alternate Forms: In a few places in Silmarillion revisions from the 1950s-60s, this name appeared instead as Ingar (MR/230, 265). It also appeared in an alternate plural form Ingwer and genitive plural Ingweron (PM/340). This last example seems to be an irregular plural, since the plural of nouns ending in -e are usually formed by changing this vowel to an -i (WJ/361). See the entry for the Quenya plural nouns for further discussion.
Conceptual Development: This name first appeared as ᴱQ. Inwir (LT1/50) derived from the older name of their leader: ᴱQ. Inwe. At this stage the name referred only the royal house of the first tribe (QL/42). In Silmarillion drafts from the 1930s, the form changed to ᴹQ. Ingwi, but still referred only to the royal house (LR/171). In Tolkien’s writing from the 1950s and later, the term expanded to include all Elves of the first tribe (MR/230; PM/332, 340).
