The 22th prince of Dol Amroth who fought at the battle of Pelennor fields in the War of the Ring (LotR/771). Tolkien said that “Imrahil is a Númenórean name” (LotR/1113), which seems to be true for the names of earlier princes as well (as discussed in the entry for Adrahil). It is not clear what this name means. Carl Hostetter and Patrick Wynne suggested (AAD/16-17) that it may mean “Heir of Imra”, with the same initial element as Imrazôr and with -hil = “heir”. See the entry on -hin for further discussion of the suffix -hil.
Conceptual Development: This name first appeared as Imrahil (WR/363), but Tolkien briefly changed it to Ildramir while he was concocting the name of Arwen, who at one point was similarly named Emrahil (SD/66). Once Tolkien settle on the name Arwen, the name of Imrahil was restored. In the drafts of the Lord of the Rings appendices, Tolkien initially listed Imrahil as a Lemberin (Nandorin) name (PM/36) before deciding it was Adûnaic.
