To speak a language, you need to at least know the words that are often used and how to put them together in sentences. Here we are talking about grammar, and while English grammar is easier than most if not all other European languages, the exceptions to the basic rules are not always easy.
All living languages change, and over the centuries, the complex grammar patterns that still exist in many European languages have reduced significantly in English. Changes come about with speakers doing things “incorrectly” until they become correct. Fifty years ago, it was considered incorrect to say It’s him, the “correct” form being It’s he, which now sounds too formal.
Whatever you want to say, just say it. Even if the grammar is “wrong”, there’s an excellent chance that you will be understood. At this website, suggestions are offered to make grammar really easy, particularly with verbs. You can choose which of these are good for you, and how to move on to standard grammar if and when you’re ready.
Many regard writing as being more formal than speaking, and for business communication and the like, that is generally the case. It doesn’t need to be that way, and in fact, writing anything as you would say it can be just as effective. One advantage with writing is that there is time to check grammar and spelling, but unless it’s important, don’t spend too much time on it. For communication, it’s just not worth it.
Learning anything that’s new means making mistakes, enjoying them, and learning from them. There should be no need to learn lists of words and rules of grammar. Learn by practicing … and doing. You will never regret it.
