جَاءَ رَجُلٌ صَالِحٌ وَعَالِمٌ
Translation: A righteous and knowledgeable man came.
Jāʾa: past verb; rajulun: nominative subject; ṣāliḥun: nominative adjective; wāw: coordinator; ʿālimun: nominative coordinate of the adjective.
Both adjectives qualify the same noun, and either can fill the adjective slot. This is an added teaching example.
