yod

root. fence, enclose

This root appears in a discussion of the possible origin of Sindarin -ion “-land”, blended with the root √YON “wide, extensive” (PE17/43). A more common variation of the latter root was √YAN, making the status of √YOD uncertain. The derivatives of √YOD are similar to those of √(G)LAN from the late 1960s which might have replaced it, but some if this roots derivatives are still useful, particularly the verb form yor- “to enclose”.
