1. Just start reading, as a list of Neurologists found the brain as an awesome vocabulary-learning machine.
While you are reading and listening, your brain absorbs words naturally, analyses the kind of expectations you have about which words usually come together.
Our brains are unstoppable from collecting statistics about words for providing us with fast speech regularly.
2. Sure, grammar is the perfect way to speak the language accurately, but you can pick it up by practicing the language naturally.
3. Try to find a language partner and practice the language with him, and concentrate on the new mouth positions.
4. Another way settled by the Linguists is to find words that have the sound little difference’s that you want to learn like “Ship, sheep”, ”fair, fare”, then try to hear and describes which one is it and find more about what if you are right or wrong.
