Conduction is when heat or electricity moves from one place to another. If you've ever felt a shock while putting on a sweater, you have participated in electrical conduction.
From Latin conducere, to bring together, conduction used to mean "safe passage or guidance from one place to another." Today, it's only used to describe events in a scientific way. In addition to heat and electricity, conduction can be applied to sound. When you and your fellow prisoners tap on the pipes to plan your jailbreak, you are using sound conduction. Good luck with that, by the way.
