finu

masculine name. Finu

A hypothetical Sindarin form of the name of Finwë, though it was never used (PM/344).

Conceptual Development: In Early Noldorin of the 1920s, the equivalent name was first given as Finweg (LB/6), but this name was soon reassigned to Fingolfin’s son (LB/21, note #29), and the Gnomish equivalent of Finwe became Finn (LB/133, 137-8). In The Etymologies from the 1930s, the name of Finwe was the same in both Quenya and Noldorin, and its true Noldorin equivalent Finw, pronounced [finu], was unused (Ety/PHIN, WEG). This remained true in Sindarin as well (PM/344).
