the Latin root in words in the english language that means speech, or talking, as it comes from the latin verb dictare, which means to say, or to speak, and the latin verb dicere, which means the same thing.
the latin root 'dict' is where we get words such as:
A sunburn or suntan focused on the left arm. It is caused by the left side of the body being the only half that gets exposed to sunlight while driving. Presumably, it would be located on the right side of the body in countries where they drive on the left side of the road.
