An element appearing in the name Rothinzil “Foam-flower”, attested in later writings (1968) as roth (PM/369, 376). This later form is incompatible with the earlier phonetic rules of Lowdham’s Report from the 1940s, which allowed only long [ō] in Adûnaic words. If this word were used in the phonetic context of Lowdham’s Report (Middle Adûnaic), it should be rôth, and in these earlier texts, the Adûnaic name of Eärendi’s ship was Rôthinzil with a long ô (SD/360). Even in later writings, Tolkien lists róþ ([rōθ] = rôth) as one of its possible forms (PM/369). See the entry on conceptual-changes-in-late-Adûnaic for further discussion.
rôthnoun. foam, white crest of waves
