The phrase "cutting in on" is often used when referring to interrupting someone. Some antonyms for this phrase are allowing, patiently waiting, or respecting. Allowing someone to finish their thoughts or conversation is a polite way to communicate while avoiding any feelings of impatience or rudeness. Patience is another antonym for this phrase because waiting for someone to finish speaking shows respect and allows everyone to contribute their thoughts. Respecting others is crucial when it comes to professional or personal settings, as it creates an environment of trust and open communication. So, instead of "cutting in on" someone, try allowing, patiently waiting, or respecting their turn to speak.
