The phrase "getting signals crossed" is often used to describe a situation where there is a misunderstanding, miscommunication, or confusion between two or more people. In order to prevent this from happening, it's important to use antonyms or contrasting words that can help clarify the intended message. Some antonyms that could be used in this context include: clear, straightforward, unambiguous, explicit, precise, and distinct. By using clear and precise language, individuals can avoid mixed signals and ensure that their message is effectively communicated to others. Overall, practicing effective communication skills can help prevent misunderstandings and improve relationships in both personal and professional settings.
