Other forms: cordialities
Cordiality is a characteristic of being friendly and agreeable. Your habit of smiling and saying hello to everyone you pass on the street is evidence of your cordiality.
People who show cordiality are polite, kind, and pleasant, but the word implies a bit of reserve: you might appreciate the cordiality among the employees at your after-school job, but your relationships with your closest friends and family are characterized by an emotion deeper than cordiality. At the root of cordiality is the Latin word cor, or "heart."
