A patronymic suffix appearing in Êruhîn “Children of God” (SD/247) and in the early phrase Indilzar Azrabêlôhin “Line of Elros [son] of Earendil” (SD/382). It apparently means “child”. A possible feminine variant -hil appears in the early name Zimrahil (SD/373), later changed to Zimraphel*.
Andreas Moehn suggested (LGtAG) that -hin might have been replaced by the suffix -thôr appearing in the later name Sakalthôr “?Shore-son”. However, the suffixes -hin and -thôr (along with -phel “daughter”) could have co-existed in the same way that Quenya suffixes Q. -ion “-son” and Q. -iel “-daughter” co-existed with the use of Q. hína “child” as a patronymic in names like Q. Eruhin.
As suggested by several authors (AAD/15, EotAL/KHÍN), -hin is almost certainly related to Q. hína, S. hên “child”, either a direct loan or derived from the same root √KHIN. Carl Hostetter and Patrick Wynne suggested (AAD/16) that the variant -hil in Zimrahil actually means “heir”, related to S. hîl, Q. hildë, and that this element also appears in Ad. Imrahil.
