SIBI-P1 G166-04
the age-abiding (thing)
| Morphological Notes | Adjective, accusative singular (ANS = accusative neuter singular; AFS = accusative feminine singular). It agrees with a feminine or neuter noun in the accusative case, describing the direct object of a verb. |
| Rendering Rationale | The adjective derives from αἰών ("age, epoch"), so "age-abiding" preserves the root idea of enduring through or pertaining to an age rather than abstract infinity. The form αἰώνιον is accusative singular (feminine or neuter in these occurrences), functioning as a direct object and thus rendered as "the age-abiding (thing)" to reflect its case and number. |
