If you edit on an English wiki you're expected to have a good grasp of the English language and to not use broken English when adding content to a page. While I don't know if a wiki that accepts your first language exists, you should try to look for one that does and if you can't find one you should stop editing on this wiki until you can improve your grammar significantly. Please read the rules to prevent something like this from happening again.
Keep in mind that this is the only warning you'll receive for bad grammar. If you ignore this warning and break this rule again you will be blocked.
