A-fāṭima is a vocative form associated with the name Fāṭimah. Omitting the feminine ending and addressing her as Fāṭim exemplifies tarakhkhīm, truncation in vocative usage. The initial hamzah draws attention in the poet’s address.
Truncation may support the verse’s meter and impart a familiar, close tone, although it does not universally imply affection. The essential grammatical observation is that the addressee’s name has been shortened in direct address.
