It's certainly interesting, frustrating, fascinating, confusing, puzzeling, challenging and many other things too.
Even if one only looks at the rough outline of how languages function and how they mutate and evolve over time, both in written and spoken form, it can be just as messy for the unaware as it can be fun.
And then there is the whole difficult subject of translations because of how many words can often have multiple meanings which don't easily overlap with similar words in other languages (because those too have multiple different meanings).
Not to forget the potential errors in how foreign words are spelled.
Like when Nightcrawer talks to Kitty and the text has him call her "kästchen" (little box) instead of "kätzchen" (kitten).
