- "Tinfang Gelion who still the moon
enchants on summer nights of June
and kindles the pale firstling star..."
- ― Lay of Leithian Canto III
The meaning of Tinfang is "star-beard" (from tinu "spark, little star" + fang "beard"; found in the Etymologies of The Lost Road). He apparently was one of those few elves who grew beards during the first age of their life, like Mahtan.
Gelion can also be found in several other compounds.
His name probably comes from an earlier poem Tolkien penned named Tinfang Warble, about a fairy-bird.
