In most people, the left side of the brain contains the person's language functions. The right side contributes to a number of functions, such as attention, memory, reasoning, and problem solving (all of which contribute to effective communication).
Language is a bit more complex; it is believed that most language processing happens in the temporal lobe, but Broca's area in the left frontal lobe is associated with spoken language, and Wernicke's area (the main area of the brain associated with understanding language) is actually between the parietal lobe and the temporal lobe.
