Consider: «قَدِمَ الضَّيْفُ. كَانَ الطَّرِيقُ مَغْلُوقًا. دَخَلَ وَهُوَ مُتْعَبٌ».
The guest arrived. The road was closed. He entered while tired.
Does “the road was closed” explain a delay or merely give background? If delay was never mentioned, a causal resumption cannot be assumed without qualification. The last segment, “wa-huwa mutʿabun,” is more clearly a nominal circumstantial clause linked by wāw and a pronoun.
The method: (1) identify each predication; (2) state what new work the next clause performs; (3) offer evidence for coordination, circumstance, or resumption; and (4) when two analyses remain possible, specify what context each requires. Rhetorical editing is an argument, not a list of labels.
