This! Coming up with meaningfull names helps you undrestand the problem and define the solution. I advise junior devs: if you don't know how to name a variable give it simple 1-letter name: a, b, x, y. When you look at the code it is immediately clear how well they understands the problem. One should be careful to avoid the naming paralasys though.
