S. Finbor pn.
A proposed son of Fingon, rejected when Tolkien decided that Fingon “has no child or wife” (PM/361 note #35). The meaning of his name is unclear, but may contain the element fin seen in the Sindarin names of the descendants of Q. Finwë (or possibly the element fîn “hair” seen in his father’s name), combined with the suffixal form of paur “fist”.
