Which of the following is NOT an interpersonal communication tool?

Employing slang is not considered an effective interpersonal communication tool because it can create misunderstandings or confusion among listeners who may not be familiar with the terminology or cultural context in which the slang is used. Clear communication is essential in interpersonal interactions, and while slang can sometimes enhance rapport in casual settings, it often detracts from clarity and precision.

In contrast, the other tools mentioned—using short, clear language, effective listening, and nonverbal cues—are all foundational elements of effective communication. Clear language ensures that the message is easily understood, effective listening allows for better engagement and response to the speaker, and nonverbal cues, such as body language and facial expressions, reinforce and complement verbal communication. Together, these tools foster clearer understanding and stronger connections between individuals.
