قَامَ زَيْدٌ وَعَمْرٌو
Translation: Zayd and ʿAmr stood.
قَامَ: past-tense verb, built on fatḥ.
زَيْدٌ: subject (fāʿil), nominative with visible ḍamma.
وَ: conjunction; indeclinable.
عَمْرٌو: coordinated with Zayd, nominative with ḍamma; its final written wāw distinguishes the spelling and is not the case marker.
The verb is stated once, but its predication includes both nouns.
