SIBI-P1 G18-05

of a good (feminine singular)

Morphological NotesAdjective; genitive feminine singular (Gr,AA,,,,GFS,). It modifies or substantivally refers to a feminine singular noun in the genitive case, indicating possession, source, or description.
Rendering RationaleThe form ἀγαθῆς is genitive feminine singular, so the rendering preserves the adjectival sense "good" while explicitly marking the genitive case with "of" and retaining feminine singular reference. This keeps the root meaning of intrinsic goodness or benefit while reflecting its grammatical relationship to a feminine noun.
