Automatic language switch [Angry poster]

Question

I've just finished my Spanish homework in my 2013 Microsoft Word, and it wasn't pleasant. I study Biochemistry along with English, Spanish, German and my native language. What gets me worked up and really has me table-flipping angry, is that every time I
hit 'enter', the language flips over to Danish.
This means I have to stare at daunting red lines in every sentence, SELECT
it when I'm done, and flip it over to Spanish again, writing in Spanish is worst, because of the way sentences using question/exclamation marks are written, it can't function without the Word dictionary co-operating. Word nowadays has no limits to
how helpful it thinks it is, so of course it'll do these small changes here and there. 
Now of course I've read up on it, and reached some kind of solution, which is changing my keyboard to whichever language I'm using. You might argue that this is the way things are most convenient for others, but I'm not asking for much here. I'm asking for
Word to NOT change the language every time I hit enter, and that shouldn't mean having to learn where all the necessary symbols are,
for every language I speak. I have no idea who came up with this idea or concept, but it's the stupidest and most crippling mistake in any software I've ever purchased. I have no idea how it's supposed to work for international students such
as myself. 
So what I'm looking for is a way to select the language in a Word document, and have it stay that way, until I change it. I'd love it if Word could figure out that I'm trying to switch languages after 3 or 4 words, and back again if I was citing, but I know
what to expect. I'm already pissed as it is with these blue lines telling me that English can only be written one way. Let's see how big an explosion comes from the red lines turning on me as well.

Answer 1

I'm not quite sure if I have understood you correctly. What do you mean by "select the language in word", do you mean the proofing language?
If yes, I would suggest you clear the "Detect language automatically" option, in the Language dialog box (Review tab>Language>Set Proofing Language). This will help to prevent Word from changing
the language.
Hope this is what you want.
