A Sindarin word for “bridge” appearing in a number of names such as Iant Iaur “Old Bridge” (SA/iant; WJ/333), Esgaliant “Bridge of Esgalduin” (WJ/333), and Varanduiniant “Bridge of Baranduin” (SD/129).
Conceptual Development: In The Etymologies of the 1930s, N. iant was glossed “yoke” and N. ianw was “bridge”, both derived from the root ᴹ√YAT “join” (Ety/YAT). Another possible precursor is G. rantha “arch, bridge” from the Gnomish Lexicon of the 1910s (GL/65), which is reduced to -rant in compounds (GL/31, 50) and is probably derived from the early root ᴱ√RAÞA that was the basis for ᴱQ. ranta “arch, bridge” (QL/79).
