English should be the main language since bitcointalk is an international forum. So what I'm suggesting is try to learn English rather complaining about its difficulty. You don't need to be a master of English language in order to participate in the discussions going on the forum. Following links will help you to learn English.
Install
Grammarly Chrome extension for your chrome browser and it also would help you to correct the grammar mistakes.
BTW English is also not my native language
