I have some knowledge to the three concepts, which are evidence, meaning, and revision. However, there is one where I know the most than the other.
To begin with, Claims that require evidences is always an important one, no matter the context. If you said something that you claim is a fact, but later provide little to no evidence to back it up, you will lose all credibility and supporters. Every time you say something to either convince others or to bring up a new idea, it is always important to back it up. No matter your background, if you are either a middle schooler or a Ph.D scholar, you should ALWAYS provide evidence. .If you back up your claim with evidence, then you will gain more creditably, support, and not make fun off. The more evidence you have, the better.
Meaning having context is an important one too. When several people are having a debate or agreeing with something, you cannot saying anything out of context. I remember one time where I was debating with someone on a video game, and someone said something completely different, and it was not even related to anything we said. Also, whatever you said could also impact a debate greatly. For example, if you are in a debate with someone that says, " Donuts are easy to make" but coincidentally, you are a baker and make donuts for a living, so you would say, "Nah man, its easy".
Lastly, writing is revision is useful too. Nobody wants to mistakes, and if you do made a mistake, you always want to fix it. This is very important for writing, since you want everyone to understand you. If you want to be seen as professional, you want to make no mistakes as possible, and put in a few big words in there as well. You could also change most of it and would be a different essay by the time you are finished with it.
This is all I know about the concepts. Most of these I knew about, and the others happens to me in my lifetime.
