Cross-questioning is a term used to describe intense questioning, often with the aim of uncovering hidden information or inconsistencies in a story. One antonym for cross-questioning is "agreeable conversation," which suggests a friendly, relaxed dialogue where both parties are actively engaged in a positive exchange of ideas. Another antonym could be "casual inquiry," which implies a more laid-back approach where questions are asked gently and without pressure. A third antonym might be "inadequate questioning," where questions are asked without sufficient depth or follow-up, resulting in incomplete answers or a lack of clarity. Ultimately, the choice of antonym depends upon the situation and the desired outcome of the conversation.
