A word for a “(professional) mariner” as a compound of ëar “sea” and -(n)dur “servant” in a draft letter from 1967 (Let/386). The suffix -(n)dur is often used for those who work on something in a professional capacity; compare ornendur “tree-keep, forester, woodsman” (NM/20). Thus ëarendur refers to people who work on the sea as their job. This word may be contrasted with Eärendil “Lover of the Sea”.

Conceptual Development: The Qenya Lexicon of the 1910s had ᴱQ. yarendila “like a sailor” and ᴱQ. yarendilyon “sailor” based on ᴱQ. Yarendl, a dialectical variant of ᴱQ. Earendel often used to mean “mariner” (QL/105). In the 1910s, ᴱQ. Earendel was not yet derived from the word for “sea”, so this association must have come from the fame of Earendel as a sailor, not from the meaning of the name itself.
