 Avempace points to the distinction between term (sound, lafẓ) and meaning (ma‛nà): man listens to a sound, and gets the meaning that he conceptualized. He may have conceptualized a first meaning but he must learn that the term has more than one meaning and how the various meanings are derivate. This learning happens by means either of a strong mind or of instruction and Avempace blames the mental deficiency of a student for not being capable of grasping the derived meaning of the term.
