oh God I bet I made like 5 mistakes in sentences with 4 words
Well, using a language repeatedly on a regular basis is the fastest way to learn, especially if it's in use with "real" people.
Reading from a textbook isn't realistic, there's certain things that are technically correct (they are right, according to a dictionary) but in practice sound wrong, and no one actually speaks that way.
The biggest way to tell the difference between someone not fluent in a language, and someone who is, isn't their spelling, nor their grammar, nor their mastery of the mechanics of the language. It's how they use things like slang, cultural sayings, and metaphors.
Speaking 100% perfect, flawless english will stand out as strange. To really get good, if intending to blend in with others, I highly suggest watching the specifics on HOW people say things, and focus heavily on sayings that don't mean exactly the same as the direct translation.
Finally, doing something you enjoy always makes it easier; it's a fun place here, and I'm sure you'll be interested enough to stay, and this should make it far easier to learn along the way.
Also, ignore my spelling, I made a special case to go back and fix all my spelling errors for this post due to the nature of the language issue. In any other post, if you see my spelling seem strange, just assume it's a personal quirk, not something to emulate.
Examples of this are "yeu" to replace "you", or "whot" instead of "what", or "helmate" instead of "helmet", and so on. Others have similar quirks (most are more common) such as just saying "u" as a shorthand version of "you", and other such things.
If you're not sure what a word means, rather than use a dictionary, I suggest a thesaurus -> Thesaurus.com | Find Synonyms and Antonyms of Words at Thesaurus.com this will not provide the definition, instead, it will provide several related terms, which will usually provide just as good an understanding, but will also increase your vocabulary even more.
Good luck and have a nice stay!
It doesn't matter if they're right. If they can't proove they're right, then they're wrong. No matter how right they may be.
