interject

The same principle applies in meetings: Bosses should hold back their opinions until others have spoken, and not interject even to express agreement.

"It's the sheer amount of time people off the playing surface are interjecting, or being asked to interject, that's making the games at times a bit of a mess."

“Grocers must eat too, my darling,” her husband interjected.

“My lady, perhaps I can be of some help,” she interjected.

“I believe Lady Constance meant that as a rhetorical question,” Penelope interjected, but the children’s enthusiasm for the topic had already taken over.
