As far as 'small' and 'little' go, 'small' is used when just describing size. 'Little' is used with another adjective when there is some emotion involved. "He was such a cute little pup." ('Cute' gives the emotion) "His dog was somewhat small." (No emotion, just size) As far as physical size goes, 'big' and 'large' are interchangeable when describing physical size. If we are talking about pure measurement or amount, then 'large' is used. "He was a big/large man - at least 100 kilos." "We spent a large amount of money on this project." "He has a big estate." "His estate covers a large area." ('Area' is a measured value)

Clark Kent was from Smallville, a fictional town in Kansas. If you don't know who Clark Kent is, your knowledge of American popular culture is lacking. (He's Supermans' alter-ego).

Thank you alex!

I think that Stephen Prefontaine had one leg longer than the other, and he was an olympic athlete.
