I am going to weigh in with the majority so far but try to crystallize the slant a bit. In other words, since you have not sacrificed any required courses i, and since you appear to have a passion for languages i, there is no reason not to follow the path you are on. And while there is certainly nothing wrong with asking the question about how it might or might not affect your college application, I would just emphasize not to look at this through that particular prism. Take what you love to learn, that is why they are called electives. FWIW, I think it won’t affect it any more or less than if you had picked another elective such as painting or computer programming, no matter what major you tell them you might pursue.
Do the same in college to the extent you can. Leave yourself open, though, to trying totally new things, like glassblowing or Italian Medieval history. Whatever catches your eye for whatever reason. Unfortunately, for most of us there just isn’t much of a chance to be that whimsical once “real life” starts.
