S. Tinúviel f. “Nightingale, (lit.) Daughter of Twilight”
The name that Beren gave to Lúthien, translated “Nightingale”, more literally “Daughter of Twilight” (S/165), a derivation of the primitive form ✶Tindōmiselde (PE19/73). It is essentially a combination of tinnu “twilight” and the suffix -iel¹, except that the archaic final -v lost in tinnu was preserved in the compound.
Conceptual Development: This name first appeared as G. Tynwfiel in the earliest Lost Tales, probably a Welsh-like spelling of the name (LT2/41), but the normal spelling ᴱN. Tinúviel emerged in the Lays of Beleriand from the 1920s and so remained thereafter (LB/22). In The Etymologies from the 1930s, N. Tinúviel had the same derivation as given above (Ety/SEL-D, TIN).
