I always used wrongly on these words. Who would please to help to summarize all of words concerning direction?
up--- upper----- upside---- upward ?
down--- under---- underside----- downward ?
front---- frontal---- foreside----- foreward ?
back---- rear---- backside------ backward or rearward ?
left---- sinister---- leftpart/leftside-----
?
right---- dexter---- rightpart/rightside?----
rightward?
You may think I am drunk, but these really make me exhausting
I did some endeavors to check each kind of six dictionaries I had, but still confused, because using methods of these words looks far different from Chinese in which each word has fixed using way with different former. But in Englsih, I always make mistake of them.
