IlmSarf is the basic Arabic grammar book known as mother of Arabic language. It is a must learning book for learning Arabic language.
It is often translated as ‘morphology’. The actual meaning of sarf is “the metamorphosing or changing of the ‘asl (base/root word) to many different examples so as to achieve meanings that could not otherwise be achieved” The science of sarf is mostly relegated to verbs and that which derives from them.
