sí

adverb. now

The Quenya word for “now” which is very well attested. In notes on demonstratives from 1968, it is a vowel-lengthened form of demonstrative si “this” (VT49/18) which seems to be a standard way of forming adverbs of time in Tolkien’s later writings; compare tá “then” (VT49/11) and yá “when” (VT49/23). This vowel-lengthening construction was explicitly described in Demonstrative, Relative, and Correlative Stems (DRC) from 1948: “The bare stems lengthened are used [for adverbs of time]” (PE23/109).

In Tolkien’s writings from the 1930s and 40s, he occasionally had sin or sín “now” with an n (Ety/SIN; LR/47; SD/247; SD/310). One working theory is that this is the form of sí when it appears before a vowel. However, in the aforementioned DRC from 1948, Tolkien had a variant form ᴹQ. sin(an) “now” using the suffix ᴹQ. -n(an), also used for adverbs of time.

Conceptual Development: The Qenya Lexicon of the 1910s had ᴱQ. tyá “now” based on the early root ᴱ√KI “this by me” (QL/46, 49). In the Early Qenya Grammar (EQG) from the 1920s he had ᴱQ. qí or qin for adverbs of time based ᴱQ. qi “this”, hence = “✱now”. However, the untranslated text Sí Qente Feanor from the 1910s seems to use sí = “now” (PE15/32, 34).

Neo-Quenya: For purposes of Neo-Quenya, I would mostly use sí “now”, but I would also use sín or sin in cases where the results are more euphonic, particularly preceding a word starting with a vowel.
