I would like to have someone help me out with how i can apply this too my german writing to better fluency in my writing and how to match.
You really do need to continue in your German lessons further before you can worry about applying and improving fluency as you do not know enough nouns, verbs, articles or simple grammar even. sinde isn't even a word in German, and seind is a noun so it would have to be capitalized. I am also guessing that English isn't your first language. So if you are studying German from English you are at a double disadvantage.
