A root meaning “all” in Tolkien’s writings from the 1930s through 1960s (VT48/25) with derivatives in both Quenya and Sindarin, the most notable being Q. Ilúvatar “All-father” (MR/39). Its earliest precursor is the root ᴱ√ILU “ether, the slender airs among the stars” from the Qenya Lexicon of the 1910s, whose derivatives include various sky-words as well as ᴱQ. Ilúvatar, since in this early period the name meant “Heavenly Father” (QL/42). The meaning of the root shifted to ᴹ√IL “all” in The Etymologies of the 1930s (Ety/IL), and it retained this sense thereafter.

This root was the basis for Elvish “love” words for all of Tolkien’s life. The root first appeared as ᴱ√MELE “love” in the Qenya Lexicon of the 1910s with derivatives like ᴱQ. mel- “to love”, ᴱQ. meles(se) “love”, and ᴱQ. melin “dear, beloved” (QL/60). In the contemporaneous Gnomish Lexicon it had similar derivatives like G. mel- “love” and G. melon “dear, beloved” (GL/57).
In The Etymologies of the 1930s Tolkien specified that ᴹ√MEL meant “love (as friend)”, and for the first time it included the derivative N. mellon “friend” (Ety/MEL); Gnomish “friend” words from the 1910s were mostly based on G. ged (GL/38). However, the same entry included ᴹQ. melindo/ᴹQ. melisse “lover” (male and female), so it seems even in the 1930s it could refer to romantic love (Ety/MEL). The root continued to appear in Tolkien’s later writings associated with “love” (PE18/46, 96; PE17/41; VT39/10).
In notes from 1959, Tolkien elaborated on the precise sense of √MEL and its role in romantic and non-romantic love:
> Love, which Men might call “friendship” (but for the greater strength and warmth and permanency with which it was felt by the Quendi) was represented by √mel. This was primarily a motion or inclination of the fëa [“spirit”], and therefore could occur between persons of the same sex or different sexes. It included no sexual or procreative desire, though naturally in Incarnates the difference of sex altered the emotion, since “sex” is held by the Eldar to belong also to the fëa and not solely to the hröa [“body”], and is therefore not wholly included in procreation ... The “desire” for marriage and bodily union was represented by √yer; but this never in the uncorrupted occurred without “love” √mel, nor without the desire for children. This element was therefore seldom used except to describe occasions of its dominance in the process of courting and marriage. The feelings of lovers desiring marriage, and of husband and wife, were usually described by √mel. This “love” remained, of course, permanent after the satisfaction of √yer in the “Time of the Children”; but was strengthened by this satisfaction and the memory of it to a normally unbreakable bond (NM/20).
Thus √MEL was close in sense to Greek “philia”, used of friendship, whereas √YER was used of “eros” or sexual desire. But in Elvish thinking, √MEL was essential for romantic love, and √YER only arose from that. Furthermore, √YER was not the most important element in the love between romantic partners, as the period of procreation and child-rearing took up a relatively small portion of Elvish lives. It was the more enduring feeling of friendship between lovers that really mattered, and thus √MEL was used of both non-romantic and romantic love, though it had not particular sexual connotation.
mith
root. grey
Tolkien introduced the root ᴹ√MITH in The Etymologies of the 1930s as a blending of ᴹ√MIS “✱wet” and ᴹ√KHITH “mist, fog”, with the derivative N. mith “white fog, wet mist” as in N. Mithrim “✱Mist Lake” (Ety/MITH, RINGI; EtyAC/MITH). As a later addition to this entry Tolkien wrote the adjective N. mith “grey”, and that was the more common use of this word in Tolkien’s later writings. In a 1955 letter to David Masson Tolkien specified that “usage suggests that MIÞ- is paler and whiter, a luminous grey” (PE17/72).

When this root first appeared in The Etymologies (Ety/PHAY), it was glossed “radiate, send out rays of light” and its derivatives were consistent with this definition, most notably in N. Feanor “Radiant Sun”. In later writings, this root was instead glossed “spirit” (PM/352), which is the connotation of most of its later derivatives. For example, the later meaning of S. Fëanor was changed to “Spirit of Fire”.
The earlier sense “radiate” probably also survived in Tolkien’s later conception, however. On MR/250, the word Q. fairë “spirit” is said to originally have had the sense “radiance”, which is precisely the meaning that ᴹQ. faire had in The Etymologies. There is also a primitive monosyllable ✶phāy “flame, ray of light” in the Outline of Phonology from the early 1950s (OP2: PE19/102). If the root meaning “radiate” remains valid, then the word S. ✱fael “gleam of the sun”, an element of S. Faelivrin “gleam of the sun on the pools of Ivrin” (the second name of Finduilas), might be a derivative of this root.
