The prohibitive لَا governs the jussive. Six ordinary addressee forms are:
AddresseeActive prohibition
you (m.)لَا تَرْمِ
you two (m.)لَا تَرْمِيَا
you (m. pl.)لَا تَرْمُوا
you (f.)لَا تَرْمِي
you two (f.)لَا تَرْمِيَا
you (f. pl.)لَا تَرْمِينَ
لَا تَرْمِ addresses a man and reflects deletion of the final weak consonant; لَا تَرْمِي addresses a woman and reflects deletion of an indicative nūn. Similar appearances can arise from different inflectional rules.
