A suffix appearing only in the name Pharazôn “Golden” and possibly also in Zimrathôn. Since the element pharaz is elsewhere defined as “gold” (LotR/1114, SD/426), perhaps this suffix can be used to form adjectives from nouns in Adûnaic. Andreas Moehn suggested (EotAL/ZIM’R) it may instead be an agental suffix, a variant of -ân.
Adûnaic
-ô
preposition. from
-ôn
suffix. adjective or agental suffix
A prepositional suffix translated “from” (SD/429). In a few places, the suffix appears with the glide-consonant v (pronounced [w]) between it and a preceding u-vowel (SD/247, 249). It is likely related to the Quenya genitive inflection Q. -o.
Conceptual Development: At an earlier conceptual stage, this suffix was a grammatical inflection, the draft-genitive -ō (SD/438).
