An Elf-lord who was a famous ship builder, whose name was translated “Shipwright” (LotR/240). His name is simply círdan “shipbuilder” used as a name (Ety/KIR).
Conceptual Development: In Lord of the Rings drafts from the 1940s, his name was first given as N. Cirdan with a short i (WR/76). His name appeared in the Etymologies as C(e)irdan (Ety/TAN), where the (e) probably indicates its development from N. ceir “ship” (later S. cair).
círdan (i gírdan, o chírdan) (shipbuilder), pl. círdain (i chírdain). Compare Círdan as a proper name.
