The grammar structure of the language you have chosen can be the same or completely different from your native language. It is important to understand the difference so that you can make sentences properly. This is also an area where people tend to make mistakes. Grammar is undoubtedly important. However, it is not necessary to learn all grammar nor is it important to learn complicated grammar right off the bat. You are a baby when it comes to language. It is ok to make 3-4 word sentences. For example, learn how to say “I eat, he eats, she eats, they eat, we eat and you eat.” Combining steps 4 and 5, you should be able to say the following: I eat bananas, he eats bananas, she eats bananas, they eat…..do you see where I’m going with this? So now, not only have you learned how to say “I eat”, but you have also learned how to make a longer sentence using words that are relatable to you. Keep making the same sentences over and over switching out the words until you are comfortable with the grammar. Rinse and repeat using different grammar structures.
