PMJI, or "pardon my jumping in," is a phrase commonly used in conversations when someone wants to offer their opinion or provide input. However, there are several other synonyms for this phrase that can be used in different contexts. For example, "excuse me for interrupting" can be used in a formal setting or when speaking to someone in authority. "May I interject" is another polite and formal way of providing input during a discussion. "Forgive me for butting in" is a more lighthearted way of saying the same thing. Regardless of which synonym is used, it is important to remember to be respectful and considerate of others when inserting oneself into a conversation.
