We only know two Adûnaic numbers: satta “two” (SD/428) and hazad “seven” (SD/247). The Adûnaic number for “one” might be *ir, derived from the root √ʔIR “one, alone”; we do know that the number “one” was the only number not considered a noun (SD/428). All other numbers are considered nouns and follow the noun they modify: gimlî hazad “seven stars” (SD/428). Formally, the number is in a genitive relationship with the noun: “seven of ships”. Most nouns that precede a number are inflected into the plural, but nouns that precede the number two are left in the singular: nârdu satta “two soldier[s]” (SD/428).
