Third-person fem. pluralلَنْ يَفْعَلْنَلَنْ يُفْعَلْنَ
The feminine singular takes final fatḥa; the feminine dual loses inflectional nūn, while the feminine plural retains the nūn of women.
لَنْ تَفْعَلَ — she will not do.
لَنْ يَفْعَلْنَ — the women will not do.
The feminine third-person plural begins with ي, unlike the second-person feminine plural, which begins with ت.
