to gulp = جَرِضَ
جَرِضَ (jarida) (imperfect يَجْرَضُ , verbal noun جَرَضٌ ) means to gulp, when occasioned by a state of anxiety or grief. It is usually followed up immediately by بِرِيْقِهِ with his spittle. Someone who does this is referred to as جَرِيْض (jareed). Like many verbs of the form فَعِلَ , we can make the verb جَرِضَ transitive by putting it on the form فَعَلَ , i.e. جَرَضَهُ he choked him (literally caused him to swallow his own spittle).
