IN UNDERSTANDABLE. For me it is understandable In. something that I can read but not understood, for all kinds of things, has to try to find the words that can be recognized, or the more close, clear and simple, and the above can be clearly understood, is not search a meaning, and be with the dictionary in hand, to search for the meaning of each word there exposed in the topic to deal with, or is this exposing, understandable and clear, not far-fetched, since if is is looking for a meaning, is because you do not know, so you have to understand and be understood by different languages or dialects.
