There are a lot of ways on how to speak the English language.
But first, you need to learn the basic concepts: Vocabulary and Grammar.
When you already mastered the two, or not actually mastered but have a very good foundation of it, this is now you start to use the language in speaking or expressing yourself. You can do that by interacting with different kinds of people especially those who use the language often.
