Words have power, especially if used correctly. This skill allows a person to influence others. Be it through the use of diplomacy when negotiating with a diplomat, duping a mark, bribing a guard, or haggling to get the best bargain from a trader.

If this skill is used against an individual to attempt to convince them to do something that they might not normally do, the defender gets to make either a Save vs. Intelligence or a Save vs. Will. The defending character gets to use whichever stat is better for him. If he succeeds, he will realize what is going on and to be able to avoid being talked into something that he might not normally agree to.
