Yes, but it's not really understood by most people (not just English). People think they are an expert at their own language in every aspect and can teach it well, but it's not so. For example when there's a non native Hungarian speaker, many of my fellow Hungarians are really bad at helping out with a difficulty, they don't understand what the person is actually asking, they go on a tangent and explain something totally unrelated, explain it wrong etc. But they are convinced they know what they are talking about.
