Many English students describe their learning goal as “I just want to be understood.” Unfortunately, they usually express this goal when they are frustrated by their errors, and are trying to justify not putting in more effort to improve. They think, “I just want to be understood, so it’s OK not to be perfect as long as a native English speaker will understand me.”
Most people can make themselves understood in any language with some basic words, hand gestures, and grunts. A simplified, broken form of a language is useful when you have no other choice. English even has a word for such a language form, “pidgin”, and it is a necessary step in learning a language fluently. But it’s not a goal.
