أَمَّا خَالِدٌ فَأَكْرَمْتُهُ، وَأَمَّا سَعِيدٌ فَلَمْ أَلْقَهُ.
As for Khalid, I honoured him; as for Saʿid, I did not meet him.
Here “ammā” and the paired subjects create overt contrast. Preposing distinguishes the judgment associated with each person and creates a structured comparison, not merely a change of word order.
Unlike the previous existential sentence, this passage explicitly signals contrast. The same broad phenomenon of altered order must be assessed through the discourse setting, not a fixed list of meanings.
