Hebrew and Arabic/עברית וערבית
Interesting video on the similarities and mutual intelligibility (or lack thereof) of Hebrew and Arabic.
hey man! i was just creeping on discussions and i noticed your comment. even though מזל טוב literally means 'good luck', in hebrew it is used only to express congratulations. if you want to wish someone good luck, one would say בהצלחה, which literally means 'with success'. אז בהצלחה!
