My thought is that inter- is one of the bound morphemes. -al might be if inter- is [STRIKE]true[/STRIKE] correct.
[STRIKE]im[/STRIKE] I'm not sure if there is any relationship between international and national (space here) (I think there is).
[STRIKE]and[/STRIKE] If yes, what is the meaning [STRIKE]that for[/STRIKE] of "inter-" [STRIKE]work[/STRIKE] with "national"?
Can anyone can give me [STRIKE]some[/STRIKE] their opinion? [STRIKE]to me[/STRIKE] :-D
