Related Words

Diplomatic, politic, tactful imply ability to avoid offending others or hurting their feelings, especially in situations where this ability is important. Diplomatic suggests a smoothness and skill in handling others, usually in such a way as to attain one's own ends and yet avoid any unpleasantness or opposition: By diplomatic conduct he avoided antagonizing anyone. Politic emphasizes expediency or prudence in looking out for one's own interests, thus knowing how to treat people of different types and on different occasions: a truth which it is not politic to insist on. Tactful suggests a nice touch in the handling of delicate matters or situations, and, unlike the other two, often suggests a sincere desire not to hurt the feelings of others: a tactful way of correcting someone.

Explanation

If you have the ability to say the right thing when two friends are fighting, making both sides happy, you are diplomatic. You have tact. You are a peacemaker. You can be diplomatic in your personal life if you’re polite, easy to get along with, and able to deliver bad news in a kind way. You can also be professionally diplomatic — diplomats are important members of the U.S. State Department. Diplomats keep the peace and maintain good relationships with other countries, even as they try to get other countries to see and do things our way. That's why keeping the peace in smaller ways is also called diplomatic.
