sír(ë)
noun. river, river, [ᴱQ.] stream
The most common Quenya word for “river”, derived from the root √SIR “flow”.
Conceptual Development: This word first appeared as ᴱQ. sīre “stream” as a derivative of ᴱ√SIŘI [SIÐI] (QL/84), and this form and gloss also appeared in the contemporaneous Poetic and Mythological Words of Eldarissa (PME/84). The form ᴹQ. siri- “river” appeared in the Declension of Nouns (DN) from the early 1930s, along with uninflected sire with short i and various inflected forms with siry- (PE21/10). The form sīre “river” with long ī appeared in The Etymologies of the 1930s as a derivative of ᴹ√SIR “flow” (Ety/SIR; EtyAC/SIR). In several notes from the mid-1960s, it appeared in monosyllabic form sír (PE17/65) or sīr (VT49/17), but it had dual form siryat from the late 1960s implying a stem form of sirĭ- and a development similar to that of DN from the early 1930s (VT47/11).
Neo-Eldarin: Its form síre is probably better known and more commonly used in Neo-Quenya. For example this is the typical form in Helge Fauskanger’s NQNT (NQNT).
sírë
river
sírë noun "river" (SIR, VT46:13), "stream" (LT1:265). Also short form sír, q.v.Compare #sirya.
wet
wet
wet, see we #2
The word for “water”, a derivative of the root √NEN of the same meaning (PE17/52; Ety/NEN). Its stem form was nen- (Ety/NEN) and its primitive form was given as ✶nē̆n, the vowel length variation due to distinct subjective nēn versus objective/inflected nĕn- in ancient monosyllables (PE21/64).
Conceptual Development: This word first appeared in the Qenya Lexicon of the 1910s with two senses: “river” and (archaic) “†water”. Tolkien indicated the two senses were based on distinct roots: ᴱ√NEŘE [NEÐE] and ᴱ√NENE respectively, with two distinct stem forms nend- and nēn (QL/64-65). The Poetic and Mythological Words of Eldarissa also mentions the forms nen (nēn-) “water” versus nen(d-) “river” (PME/64-65). In the English-Qenya Dictionary of the mid-1920s Tolkien had both nēn “river” (PE15/76) and nēn “water” (PE15/78), but in the Early Qenya Grammar he had only nēn “water” (PE14/43, 72), also appearing as nen “water” in documents on The Valmaric Script from this period (PE14/110).
In the Declension of Nouns from the early 1930s, Tolkien had ᴹQ. nēn “water”, but in this document it had nēn- with long ē in its inflected forms as well (PE21/23). In The Etymologies of the 1930s, however, uninflected nén “water” had a stem form of nen- with short e (Ety/NEN), and the reasons for this variation was discussed in Primitive Quendian Structure: Final Consonants from 1936, the nominative/objective distinction noted above (PE21/64). This seems to be the paradigm Tolkien stuck with thereafter, as evidenced by S. nen “water” rather than ✱✱nîn.
