Mulmiʿ characterizes the female; aḥqab is the male associated with her. Lāḥahu here suggests bodily leanness. Ṭard means driving away; ḍarb, striking; and kidām, biting or bruising with the teeth.
The coordinated verbal nouns in ṭardu al-fuḥūli wa-ḍarbuhā wa-kidāmuhā accumulate physical actions. The passage thus conveys prolonged contest and exhaustion, not a single isolated encounter.
