I see French mentioned a lot. I only speak it a little so I look to more proficient speakers to correct me but in my basic ability with the language I find it much more limiting than I thought. Example, some English and their equivalents in French:
I study / J’étudie.
I do study / J’étudie
I am studying / J’étudie
Now with tone of voice to convey the varying emphasis between the examples the subtle differences in meaning are easier to show but I think if you're a native English speaker you'll pick up on them from just the writing. The first conveys that studying is an activity you do, the second is the same but with a connotation of refuting the opposite. E.g. "I've never seen you studying" / "I do study!" And the third of course describes states what you are doing right now.
You can swap in whatever very you like really: "I garden" (describing a hobby); "I do garden" (Refuting the negative), "I do gardening" (answer a question such as what do you for fun, similar to the first); "I am gardening" (why do you think I am covered in soil?).
French doesn't seem to have that but it may be that I'm just too basic in my knowledge. What I found in general with French is that the vocabulary is so much more limited. Example, we say moth and butterfly. Too different things. They say
papillon and
papillon de la nuit. That must be why French people talk so quickly - they have to use more words to say the same thing. I don't hate the language, I don't know it well enough to judge it fairly. But these are my impressions. I also found Portuguese and Spanish a bit limited in the same way. Russian in some ways feels like the closest to English in a way, in that it is also very complex and seems to have a big old vocabulary. Or maybe it just feels that way as a student.
Mandarin somebody mentioned and I actually quite like it. It's very logical and consistent compared to most languages, which I guess is what happens when you have a very long unified history and not too many people successfully invading you from dissimilar language groups. It is the poster child for why Phonetic alphabets are better, though.
It's not really "hate", but you cannot convince me that Welsh isn't just an elaborate hoax.
I can. By introducing you to the Welsh.
