Sarn Athrad means "Ford of Stones" or "stony ford" in Sindarin (sarn + athrad).
A ford across the river Gelion translated “Ford of Stones” (S/92), its name is a combination of sarn “stone” and athrad “ford” (SA/sarn, thar).
Conceptual Development: The name dates back to the earliest Lost Tales and developed as follows: G. Sarnathrod “Stony Ford” (LT2/236) >> N. Sarn-athra/Athrasarn (SM/133, 244) >> N. Sarn Athrad “Stone of Crossing” (LR/406) >> S. Sarn Athrad “Ford of Stones” (S/92).
