To make something easier, or at all possible, to comprehend. The opposite of incomprehensibilization. Comprehensibilization can be a matter of explaining something in simpler terms and with better examples. It can also be a matter of creating new models and concepts that are easier to learn and thus in the ling term easier to comprehend. In many cases, the process of inventing/discovering an idea and refining it may be the easy part, far easier than making it comprehensible to a reasonably wide audience. This is and remains an ongoing struggle for greater understanding.
