I think many, many native speakers would struggle with those too so if you're at that level you're doing really well. Congrats!

Definitely's spelling is easier if you recognize that the root word is finite. De-finite-ly.

It's not finate. That's not a word (unless it's some bullshit word no one ever uses).

So mostly ~~you hate~~ French :)

I've never heard anyone of any native language pronounce it fack-aid? The English speakers I hear always say fuh-saad. Or are you saying that fack-aid is how you pronounce it and you struggle with fuh-saad?

Mispronunciation. "Mis" isn't a word, but a prefix (or something) that gets attached to another word to modify it. Since it's not its own word, it gets prepended to the root word ("pronounce" in this case) without a dash.

German would always have the capital. In English, proper nouns get capitalized. There's an official list, I'd bet, but a good rule of thumb is that titles (books, movies), specific place names (Germany, London, Abbey Road), people's names (Bob, Reiner), and "I" (but not "me" etc) are put into "Title Case". (Title case wouldn't be capitalized, I just typed it that way to demonstrate it)

I actually like a lot of the German capitalization rules. On the internet, a lot of people will be more casual with capitalization. Some people will capitalize "important words", or things that aren't proper nouns but have a different meaning than usual...but these kinds of things are improper.

As for routing (and router, and heck...route in general)...both are correct pronunciations of this "ou". I think "au" is more common for networking in North America, and "oo" is more common in other English-speaking countries (the UK, Australia...).

As for "route" as in "Route 56", I tend to hear and say both/either (I'm in North America).

Sorry it's so inconsistent!

I struggled with that as a native english speaker at first

But now I realize the correct pronunciation sounds super cool
