i have downloaded arabic onto my mac so that i can type in it for class. however, now when i use safari some websites (like youtube and google) are in arabic, even when i have english chosen on the top upper right bar. how can i fix this so that websites appear in english?
Make sure that in system prefs/language & text/language you have English at the top of the list and not Arabic. This section has nothing to do with typing. For that you only check a box in the Input Sources section.
