The word root of "empathetic" is "empath".

Empathy is the ability to understand and share the feelings of another person. It is derived from the Greek word "empatheia", which means "feeling into".

In the context of sales, using an empathetic tone means that the salesperson should try to understand the customer's needs and feelings, and communicate in a way that shows that they understand. This can help to build rapport with the customer and make them more likely to buy the product or service being sold.
