Final answer:
Listening is the receiving part of communication, essential for understanding the message and emotions conveyed by the speaker.
Step-by-step explanation:
Listening is a fundamental aspect of communication. It is the receiving part of communication, where we pay close attention to the speaker, understand their message, and respond appropriately. When we listen, we not only comprehend the spoken words but also grasp the underlying emotion and tone, which helps in building a strong rapport. As opposed to sending which is about conveying messages and ending which signifies the conclusion of a communication exchange, listening ensures that communication is effective and participatory.
