@abubakardu English grammar is extremely difficult to learn. In your question you have a grammatical error. You said 'spoking'. The correct word is 'speaking'. Spoking is not a word. For learning grammar you should learn punctuation, compound words and conjunctions.

This is a *huge* question. Learning a language has four parts: listening, speaking, reading and writing.

There are many English teachers on YouTube who teach vocabulary and grammar. These are some of my favourites, and there are many others.

You can also listen to other YouTube channels in English. Search for any subject you're interested in and listen to it in English. This will help you to build an English vocabulary in the subject (or subjects) that you like to talk about.
Listening to comedians is a great way to build your vocabulary because comedians make jokes about a lot of different subjects and they talk the way people talk everyday.
If your English level is advanced enough, you can listen to the news in English. World news will give you a broader vocabulary, and they speak a slightly more formal English. (And based on the English in your question, I think that you are advanced enough.)
Also, listening to audiobooks will help to improve your vocabulary and your pronunciation. Stephen Fry has a wonderful accent and he has recorded 30 audiobooks. Here is a list of the audiobooks read by Stephen Fry.

Reading is also a great way to build your vocabulary. Here are nine books that are recommended for English learners.

If you need a good English dictionary, I recommend the Oxford Learner's Dictionary. It is designed for English learners, and I use it myself.

Oh, by the way, I'm a native English speaker, which means that I've been speaking English for 59 years.

@abubakardu You're very welcome.

That's great! I've never seen al Jazeera before, but I watched it for a couple of minutes and it is excellent.
