སྐྱེས་བུ། སྐྱེས་པ། སྐྱེས་མ།

skyes bu, skyes pa, skyes ma: 

Could it be that skyes bu “mankind” literarily means “a born progeny” (cf. bu pho and bu mo)? Likewise skyes pa (“man”) means literarily “a born male,” and skyes ma “woman” literarily means “a born female”? Cf. skye ba, skye bo, skye dgu/rgu.
