A prepositional element only attested in the late (1968) word obroth “fore-cutting” (PM/376), referring to the wake before a boat, so perhaps meaning “*before”. It appears only as a suffix, but in the earlier Adûnaic grammar of Lowdham’s Report from the 1940s, Adûnaic prepositions are used as suffixes (SD/435). This preposition also differs from the earlier phonetic rules of Lowdham’s Report, which allow only long [ō] in Adûnaic words. If this preposition were used in the grammatical and phonetic context of Lowdham’s Report (Middle Adûnaic), it might be the suffix *-ôb. See the entry on conceptual-changes-in-late-Adûnaic for further discussion.
