الرَّابِعُ: عَكْسُهُ، نَحْوُ: «ضَرَبْتُ وَأَكْرَمَنِي زَيْدٌ».
Translation: Fourth: the reverse of the third; the first verb seeks the noun as object, the second as subject, as in “ضَرَبْتُ وَأَكْرَمَنِي زَيْدٌ”.
The first verb has “I” as its subject and requires an object. The second verb requires a subject, supplied by overt «زَيْدٌ».
