A more thorough explanation:

A subcommittee is a smaller group within a larger committee that is assigned to investigate, consider, or take action on a specific issue or topic. It is a subordinate group that reports back to the larger committee.

For example, a legislative committee may create a subcommittee to focus on a particular area of legislation, such as healthcare or education. The subcommittee would research and analyze the issue and then report back to the larger committee with their findings and recommendations.

Another example is a parent-teacher association (PTA) forming a subcommittee to plan a school fundraiser. The subcommittee would be responsible for organizing the event and reporting back to the PTA with their progress and results.

Overall, subcommittees are useful for breaking down complex issues into smaller, more manageable parts and allowing for more focused attention and expertise on specific topics.
