-thôr Reconstructed

suffix. ?-son

An element appearing only in the name Sakalthôr (UT/223). Though unglossed, his Quenya name Falassion seems to be falassë “shore” + -ion “son”, so perhaps -thôr is a patronymic meaning “son”, the masculine equivalent of -phel “daughter” appearing in Zimraphel “✱Jewel-daughter”, as suggested by Andreas Moehn (EotAL/THUR).

narak

noun. eagle

A noun attested only in the plural subjective form Narīka “eagles” (SD/251). This formation is peculiar, because it seems to be a neuter subjective form, but the names of animals are generally common-nouns, as pointed out by Andreas Moehn (EotAL/NAR’K). If it were declined as a common noun, the subjective plural should be ✱narkim: compare Nimir “Elf” whose subjective plural form is nimrim (SD/436). Perhaps when Narīka was written, Tolkien had not finished working out the Adûnaic gender and case system.
