The name of Aragorn’s lineage after he became king of Gondor, a Quenya translation of “Strider” (LotR/863). As suggested by Hammond and Scull, this name appears to contain telco “leg” (RC/580). If its translation is accurate, it is probably a compound of an otherwise unattested verb ✱telconta- “to stride” (“leg it”) and the archaic agental suffix -r(o).
Conceptual Development: In Lord of the Rings drafts, Tolkien first gave this name as ᴹQ. Tarakil “Trotter” >> Tarakon >> Tarantar, before settling on the final form Telkontar >> Telcontar (WR/390, 395).
Telcontar masc. name "Strider" (MR:216). This word may suggest a verb *telconta- "to stride".
