The ability to understand another person's feelings and attitudes is termed empathy. Empathy involves not only recognizing emotions in others but also being able to resonate with and share in their emotional experiences. This trait allows an individual to connect deeply with another person’s perspective, fostering stronger interpersonal relationships and effective communication.

In contrast, compassion generally refers to a desire to help those who are suffering, which may or may not involve a direct understanding of their feelings. Sympathy, on the other hand, involves feeling pity or sorrow for someone else's misfortune, but it does not require a shared emotional experience. Understanding can denote a broader comprehension of a situation or concept but lacks the emotional depth that is central to empathy. Each of these terms has distinct nuances, but empathy is specifically focused on emotional insight and connection.
