A Sindarin translation of the name of Sam’s son Frodo appearing in Tolkien’s unpublished epilogue to The Lord of the Rings and in the King’s Letter (SD/126, 129), distinct from Frodo Baggin’s Sindarin name: Daur. The name of Sam’s son appears to be a combination of the prefixal form ior- of iaur “old” and the lenited form of sael “wise”, also seen in the Sindarin translation of the name Samwise (Halfwise): Perhael.
Conceptual Development: In earlier versions of the epilogue the name appeared as N. Iorhail (SD/117), which seems to contain an earlier word N. sail “wise” based on Noldorin phonology: see N. [[n|[ai] revised to [ae]]].
iaur (“ancient, old”) + sael (“wise”)
