turn-yieding cue
When you are speaking to one or more people, it can be understood that if you are speaking, it is your turn in the conversation. To yield means, basically, to give up or relinquish such as “Yield” sign you may see on the side of the road while riding in a car on a roadway. To yield, on a roadway means to give other traffic the right of way or their turn at passage through, say, an intersection or roadway. Thus, when you ask a question during a conversation, what you are doing is relinquishing (or yielding) your turn at speaking. Thus, the proper response is “turn-yielding cue.”
