[quote="SuperBabySimba"]I always thought it was just Zazu yapping on his romantic visions leading it to be about getting married over-all. Especially as, in the Finnish dubbing, his literal words are "You've been promised to each others." in a questioning tone, as if asking Simba and Nala if that's what they're going to be - because he himself thinks they're so potential and cute and all.[/quote]
That would be a good observation if not for this line: "It's a tradition going back generations."
It's not much of a "tradition" if it's never actually been used and Zazu just decided to say it because he thinks they make a cute couple.
Also, the movie was originally made in English, by an American animation company. So even if the translation is somewhat different in Finnish (or any other language really), it doesn't really change much as the original version pretty clearly states they were meant to be married (betrothed, intended, affianced, etc).
