Etymology
Polarography comes from polar ('pole' or 'positive/negative side') and -graphy ('writing' or 'recording'), the same graph you see in photograph. So polarography literally means 'recording the poles', which helps you remember it is a method that records how electric current changes with voltage to measure substances.
