Ad. #Êruhin pn. (strong-I gendered common) “Child of God”
A title for the race of men as the children of Êru “God” (SD/247). It is only attested in the plural Êruhîn (SD/311, 358) and subjective plural Êruhînim (SD/247-8) forms “Children of God”. The suffix -hin seems to have been a general patronymic in Adûnaic used for lines of descent, also appearing in Indilzar Azrabêlôhin “*Line of Elros [son] of Earendil”.
Conceptual Development: This name first appeared as Eruhil(di) (SD/341, 399), probably incorporating ᴹQ. hilde “men”. In these early appearances Tolkien may have conceived of this as a Quenya word before introducing its Adûnaic form Êruhîn. In its early appearances the latter name sometimes had a short initial E: Eruhîn (SD/358), possibly another transitional form resembling later Sindarin Eruchîn. In still later writings, Tolkien coined a Quenya word Q. Eruhin of the similar meaning, encompassing both Men and Elves.
