The three affirmative passive feminine third-person forms are:
Word / formMeaning / explanation
Singular: تُفْعَلُshe is / will be acted upon.
Dual: تُفْعَلَانِthose two women are / will be acted upon.
Plural: يُفْعَلْنَthose women are / will be acted upon.
The third-person feminine plural is يُفْعَلْنَ, not تُفْعَلْنَ. Its initial يُ and feminine plural suffix ـنَ identify this paradigm position. The final root consonant is sākin before the nūn of feminine plural.
