First notebook entry: Introducing myself

I learn am learning English because it requires me to communicate with people because the English language became it is an international language and I want to be able to communicate with people. . I don't want to ignorance of the language was to be a barrier for me and for my future professions in my career.

Good work!

Adding -ing to the end of the verb forms one of the progressive tenses. One uses the progressive tense to talk about on-going actions. You are currently learning English, so it is on-going.

Also, there are two ideas in the first sentence: 1. to learn English because it is an international language and 2. to learn English because you want to communicate with people. I seperated those two ideas with an and. This helps the reader better understand what you are doing and why you are doing it. 

Was is the past tense of to be. After I want you can use the infinitive of any verb. For example: I want to run, I want to eat, I want to live.

Lastly, career is a noun that implies your future professions.

Cheers!

...or here is another possible way of your second sentence by me:

I don't want wouldn't like if to ignorance the lack of the my language knowledge was a barrier for me and for my future qualifications.

In this case I've tried to retain the original wish of your expression, the conditional mood. I think in this case we can't use the "want" word. The expression "I wouldn't want if" sounds strange to me.

Now I'm really curious what a native speaker thinks about the sentence.

I learn English because it requires me is required to communicate for communication with people because the as English language it became an international language. I don't want to ignorance the lack of the my language knowledge was to be a barrier for me and for my future professions qualifications.

Hi Sabina, this is my version. I'm not sure it is perfect as I'm not a native English speaker, nor a professor of grammar, but I think it sounds better like this. I hope someone with more knowledge will check your original and my corrected text out.
