This word first appeared as ᴱQ. ar (arn-) “child” in the Qenya Lexicon of the 1910s (QL/32) and its stem form arn- appeared in the Poetic and Mythological Words of Eldarissa (PME/32). The word reappeared in Early Qenya Word-lists of the 1920s (PE16/135), but in the Early Noldorin Dictionary the Qenya form was given as arne. In the Declension of Nouns from the early 1930s, the word appeared as ᴹQ. aran (arn-) “child” (PE21/19), but there is no sign of it from this point forward, probably displaced by Q. aran “king”.

A word for a (male) child in The Etymologies of the 1930s added to its entry when the meaning of the root ᴹ√SEL-D was changed from “daughter” to “child” (Ety/SEL-D). It was written above its feminine equivalent ᴹQ. selde and an apparently neuter form ᴹQ. selda was written to the right, making seldo likely the masculine form as suggested by Carl Hostetter and Patrick Wynne (EtyAC/SEL-D), hence = “✱boy”.

An adjective or pronoun for “all the, the whole” appearing in Demonstrative, Relative, and Correlative Stems (DRC) from 1948 as a combination of ᴹQ. il(u)- “the whole” and ᴹQ. qa- “each, every, all” (PE23/106). It also functioned as a prefix of similar meaning (PE23/101). As an adjective Tolkien specified ilqa was used with singular nouns and always without the article, as in ᴹQ. ilqa nóre = “all [the] land” (PE23/106). It could be used pronominally to mean “the whole (situation)” (PE23/105).
Conceptual Development: In drafts of DRC, ilqa meant “every, each” before being revised to qa(qe) (PE23/101 note #36). In DRC, primitive ᴹ√kwā- meant “all”, possibly related to ᴹ√KWAT “fill” (PE23/101). However, in The Etymologies of the 1930s ilqa was instead “everything”, because in that document ᴹ√KWA meant “something”, so that il-qa = “✱all things” (Ety/IL; EtyAC/KWA). The word ilqa was translated as “all” (pronoun) in ᴹQ. Fíriel’s Song, also from the 1930s (LR/72).
Neo-Quenya: In Tolkien’s later writings, IL was “all” (VT48/25) and √KWA was translated “whole, complete, all” (VT47/7, 17), but I think ilqua might still be used for “all the, the whole” with a reversal of the meaning of its elements.
