A weathercock is a tool that is mounted on top of a tower or building that shows the direction of the wind. People use it to predict the weather or the wind direction. In everyday conversation, we might use the word "weathercock" to describe a person who changes their opinion or position frequently, as if blown around by the wind. For example, you might say "I can never tell what he really thinks about things--he's a bit of a weathercock."
