Other forms: simpatica; simpaticos
If you have a lot in common with someone, and the two of you get along really well, you can describe the person as simpatico.
Use this adjective for wonderfully agreeable people: "I had my favorite bus driver today — she's totally simpatico!" You can also describe a relationship as simpatico when people really get each other. If you and your best friend share many of the same interests and opinions, and communicate so well you practically read each other's minds, your friendship is simpatico. Meaning "sympathetic" in both Spanish and Italian, sympatico is rooted in the Greek sympathes, "fellow feeling."
