There is a video (https://youtu.be/UFuxlnUeGmg) talking about a tip to start a speech or an essay.
When you give your opinion, it's a very good idea to start by saying what is good about the opposite opinion.
To illustrate, consider this example
Although some people love eating at home, I prefer eating at a restaurant.
and then she said
So, I have here my words: "Although", "even though". What follows is a subject. A subject can be words like: "some people", can be "he", "she", "we", "the teacher". Okay? So, the subject is pretty much a noun.
"pretty much" means "basically" or "mostly" and indicates there might be an exception, which is not a noun or noun phrase.
In terms of this grammar formula (here is a discussion about if this kind of thing could be called grammar formula)
"Although" + subject + verb, subject + verb
in what situation the subject might not be a noun or noun phrase?
