جَاءَ الْوَلَدُ يَبْكِي.
The boy arrived crying.
'Yabkī' is an affirmative imperfect expressing a concurrent state. Ordinarily, a direct circumstantial wāw is not added before such a positive imperfect. In «جاء الولد وهو يبكي», the addition of 'huwa' changes the inner structure into a nominal clause.
This is not merely an insertion of wāw. The first sentence has a verbal circumstantial clause; the second contains a nominal clause whose predicate is an imperfect verb.
