"Catch at" means to grasp or seize something quickly or eagerly. For example, if a student is struggling to learn a new concept and finally understands it, they might catch at the new knowledge and feel excited about it. The expression can also be used to describe someone who seizes an opportunity or takes advantage of a situation. It's important to note that "catch at" often implies that the action is sudden or unexpected, and may not be entirely planned.
