Other forms: diplomacies
Diplomacy is the art of helping groups to get along and even work together. If you have a gift for diplomacy, you can get bickering siblings to cooperate.
The word diplomacy comes from the French word diplomatie, which means “diplomat.” A diplomat lives in a foreign country, fluent in its language — and culture. The job of a diplomat is to practice diplomacy among nations, understanding the concerns and needs of all and, if possible, guiding them toward decisions that are mutually agreeable.
