In his book, Asrar al-Balagha (Secrets of Eloquence), Abd al-Qahir al-Jurjani devotes a long chapter to discussing the two terms. Majaz Aqli (Mental Trope) and Majaz Lughawi (Linguistic Trope). These are two basic terms in classical Arabic rhetoric. Despite their importance, they are normally totally ignored in modern research. Sometimes they are even wrongly interpreted. In this presentation, I will attempt to analyze the exact approach of Abd al-Qahir al-Jurjani to these two terms. Abd al-Qahir hints at the fact that the two terms are related to the metaphor. Some modern scholars have mistakenly understood that the mental trope indicates what was known as "the old metaphor" (A is ascribed to B although B does not have A in reality; such as "the hand of the death"; death has no hands in reality); while the linguistic trope indicates "the new metaphor" (A is used instead of B; such as "I saw a lion"; meaning that I saw a brave man). In this presentation, I will argue that the linguistic trope often indicates the "verb-metaphor"; while the mental trope is not related by any means to the metaphor.
