Polite. part of speech (adjective). Defined as showing good manners towards others.

Everyone likes to be acknowledged when they go over and above to make one feel special. A verbal "thank you" is always pleasant and well received; however, a handwritten thank you note is even better!

I clearly work in an office with the Queens of Etiquette, as thank you notes are on continuous circulation around the office. It is always a treat to come into the office to find a sweet note at your work station.
