Early Quenya
titinwe
noun. small star, a sparkle of dew
A word appearing as ᴱQ. titinwe “small star, a sparkle of dew” in the Qenya Lexicon of the 1910s, derived from the early root ᴱ√TINI “twinkle” (QL/92). It seems to mean “✱small sparkling thing”, and is a diminutive of ᴱQ. tinwe.
Neo-Quenya: I think this work can be salvaged as ᴺQ. titinwë based on the later word Q. tinwë, which still means both spark and star.
. In First Age North Sindarin this word appears as tim (MR:388). Archaic tinw, so the coll. pl. is likely tinwath. 3)
