lame
尣 centers on physical impairment of the legs, specifically being lame or having difficulty walking.
尣 is a pictograph of a person with bent or uneven legs, representing lameness. The top ハ-like strokes suggest the upper body or arms, and 儿 represents the legs in an impaired stance.
The top ハ looks like a person's arms, and the bottom 儿 looks like legs that are bent or uneven. Picture someone trying to walk but their legs are lame, so they hobble along.
For オウ, imagine a person with lame legs saying 'Ow!' as they try to walk: Ow -> オウ, and the pain makes them lame.
